The Best Backpacking Backpacks for Thru-Hiking in 2025

Your backpacking pack is one of the most important components of your backpacking setup. Your style of pack goes hand in hand with your style of hiking. They need to complement each other, regardless of whether you’re a luxury camper or an ultralight fast packer. The best backpacks for thru-hiking are the ones that fit your specific wants and needs.

We based our 2025 list of the best backpacking backpacks on recommendations from Trek writers, our gear testing team, our annual Appalachian Trail thru-hiker survey, and an extensive comparison of price, weight, features, durability, and intended use.

That said, there’s no one-size-fits-all. There are a lot of styles of backpackers, and a lot of styles of packs. Remember that gear trends come and go, and ultimately it’s up to you to decide what works best for your packing style and intended use. Did we leave out your favorite? Feel free to yell at us in the comments. We’re always open to testing new gear.

A note on pack volume: where available, we broke the pack capacity down into the volume of the main compartment + volume of exterior pockets. This wasn’t possible in all cases as some manufacturers (looking at you, Osprey and Granite Gear) only report the overall volume.

Best Backpacking Backpacks for Thru-Hiking in 2025

Gossamer Gear Mariposa (Best Midweight Pack)

best backpacking backpacks

Best backpacking backpacks for thru-hiking: Gossamer Gear Mariposa.

MSRP: $315
Weight: 34.2 oz (medium w/ medium straight belt)
Volume: 36 + 24 liters
Maximum load capacity: Up to 35 pounds

Why We Love This Pack

There are lighter 60-liter packs on the market, but none that carry a full load, easily swallowing even the bulkiest of bear canisters, as comfortably as Gossamer Gear’s Mariposa. GG updated its flagship pack in 2024 with a redesigned frame and load lifters, as well as more choices of hip belt size and style. The Mariposa also now comes in a cool new colorway, which is always exciting.

For thru-hikers who want the supportive, well-ventilated comfort of a fully-featured pack, only without all the unnecessary bells and whistles (and weight), look no further than this fan favorite. The Mariposa seems to do everything well, managing to strike a delicate balance between streamlined simplicity and luxurious comfort. A feature-rich, quality pack at a fair price.

Features

  • Hip belt: Choose between straight or curved and customize the size. The 2024 update saw the introduction of the PVT frame, which is meant to pivot with your stride for more comfortable weight distribution. Yes, it has pockets.
  • Eight pockets: Two large, asymmetrical mesh side pockets are accessible while wearing the pack. There’s also a third stretchy side pocket on your right side as you wear the pack — plus a large front pocket, a top lid compartment, two hip belt pockets, and the iconic back pocket where the removable sit pad lives.
  • Customization: Three torso lengths, three hip belt sizes, and two hip belt styles for a more custom fit.
  • Breathability: Airmesh fabric on shoulder straps and hip belt for less friction, more cushion, and more comfort.
  • Attachments and extras: Trekking pole hardware for storing them outside the pack, plus a lash loop for an ice axe, a sit pad that doubles as extra back cushioning, and a removable stay.

Nobody’s Perfect

Gossamer Gear now sends their medium and large packs with a medium straight hip belt installed and their small packs with a small/medium curved hip belt, as these sizes fit most customers. If you want a different hip belt size or style, you’ll have to purchase it separately and then return the installed version to the company for a refund. Not a huge deal, just know that the process will be a little clunky if you need to swap.

The price and weight of the Mariposa both increased a little bit with this year’s redesign.

ULA Circuit (PCT Thru-Hikers’ Favorite Pack)

best backpacking backpacks for thru-hiking

Best backpacking backpacks for thru-hiking: ULA Circuit

MSRP: $300
Weight: 38.5 ounces
Volume: 39 + 29 liters
Maximum load capacity: Up to 35 pounds

Why We Love This Pack

The ULA Circuit has been the highest-rated pack on the PCT for four years running, according to Halfway Anywhere’s most recent (2023) PCT thru-hiker survey. While it might not be the lightest pack on the list, the Circuit makes up for this in comfort, carrying capacity, and durability. It has an excellent carrying capacity, coming in at 68 liters (internal + external) and a max load of 35 pounds — perfect for the longer food carries and dry stretches common on the PCT or CDT.

An aluminum stay, carbon fiber loop, and dense foam panel form a rigid frame that molds to your back over time. This makes the pack incredibly comfortable, keeping weight stable and as close to your back as possible. The Circuit is made from 400D Robic fabric, ULA’s fabric of choice due to its toughness per ounce. ULA’s famous customer support also means that once you’ve given your pack a thorough beating by means of a thru-hike, you can send the pack back for a free tune-up to get it back to full health.

There is also an Ultra version of the Circuit available, which is a little more expensive but cuts a few ounces and is more weatherproof.

Even the standard Robic Circuit now features an UltraStretch mesh pocket thanks to a 2024 update, which also included standard ice axe/trekking pole loops and attachment points for optional Y- and bottom strap kits.

Features

  • Roll-top closure and compression straps: The roll-top closure, paired with the top and side compression straps, gives this bag flexibility based on the volume of your bag. This allows for big carries out of town but a more snug pack when returning to civilization.
  • Dual hip belt pockets: The large hip belt pockets are big enough for the largest of phones and the hungriest of snackers.
  • Large side pockets: The side pockets are big enough to carry two SmartWater bottles each, can be cinched down with the built-in drawstrings, and are positioned well for easy reach when hiking.
  • Large mesh front pocket: The elastic front pocket and drawcords allow for easy access to rain gear or storage of bulky items.
  • Padded contoured shoulder straps and back: The padded back panel and shoulder straps are very comfortable, if not a little sweaty.
  • Hydration bladder, hand loops, stash pocket: The pack comes with a few extra features that can be removed to save about three ounces (85 grams) of weight.

Nobody’s Perfect

This pack isn’t the best in wet conditions as the fabric soaks through and gets heavy, in addition to the need to carry a bag liner/trash compactor bag (remember that Ultra version?). The back panel and shoulder straps can get very sweaty and are dirt magnets, so make sure to put the pack down on its front/bottom.

Osprey Exos (Men’s) | Osprey Eja (Women’s) (AT Thru-Hikers’ Favorite Pack)

Best backpacking backpacks for thru-hiking: Osprey Exos/Eja.

MSRP: $240
Weight:
43 – 46 ounces
Volume: 48 liters (38L and 58L versions also available)
Maximum load capacity: Up to 35 pounds

Why We Love This Pack

Osprey has redesigned this popular pack a few times over the years with more durable face fabric, updating the mesh front pocket, and finally reintroducing hip belt pockets after their inexplicable elimination. Throughout it all, this pack has remained a perennial favorite among thru-hikers (the Exos and Eja combined have ranked as the most popular pack on the AT nearly every year since we started tracking these things with our AT hiker survey in 2015). It’s an ideal middle-of-the-road model, striking a nice balance between luxe and lightweight, built with lighter materials and some pared-down features.

Durability has increased over the years with the aforementioned material updates, and the Exos’s trampoline-stye suspension is famously comfortable. The ventilated mesh system keeps your back cool while holding the pack tight against your body. The Exos also comes in a 38 and 58L variety, and the women’s version can be found here. Even though the Eja was released a few seasons ago, the Exos has worked well as a unisex pack since its initial release.

Eja / Exos Pro

Osprey also offers a 55L “pro” version of this pack with a more minimalist design and lighter materials. The XS/S Eja Pro weighs 31 ounces, while the M/L Exos Pro weighs 35 ounces. Both packs cost $290. That’s roughly a three-quarter pound weight reduction for an extra $50, which is a very reasonable market in the UL world. Like the standard version, the Pro has a removable lid. The lidless pack’s total weight can drop to two pounds or less, aka proper ultralight territory — an extraordinary achievement for a pack with such a well-developed suspension system.

We haven’t tested the Eja/Exos Pro yet, but some users say the water bottle pockets are larger and stretchier than on the original, addressing one of the biggest pain points associated with this pack. You can find other backpacks in this price and weight range, but probably not with a suspension system to rival Osprey’s famous comfort and breathability.

Features

  • Removable top lid: The “brain” is a luxury we don’t often get with the lighter weight packs. This version has two zippered pockets. It can be removed to save weight, and hikers can instead utilize the flap underneath for protection over the top of the pack.
  • AirSpeed suspension: Osprey’s proprietary suspension system is comprised of tensioned mesh with generous space for airflow in every direction.
  • Adjustable hip belt: Osprey’s update to this pack came with an adjustable hip belt, good for hikers dropping serious pounds on a thru-hike.

Nobody’s Perfect

We’re stoked that the hip belt pockets are back, but they’re too small for a cell phone. The side water bottle pockets are tight and difficult to access while the pack is on (the best method is to feed the bottle through the little hole in the front part of the pocket). The compression straps are a bit fiddly and run right over top of the water bottle pocket, putting the functionality of both features at odds with each other.

Osprey Aura AG 65 (Women’s) | Atmos AG 65 (Men’s) (Best Fully-Featured Pack)

best backpacking backpacks

Best backpacking backpacks for thru-hiking: Osprey Aura/Atmos.

MSRP: $340
Weight:
71-77 ounces
Volume:
65 liters
Maximum load capacity: Up to 40 pounds

Why We Love This Pack

The trend is lighter weight, simpler packs, and each year, more new thru-hikers lean in that direction. However, for backpackers looking for more comfort with heavier loads, padding, and organization options, this is a great option and continues to be one of the best and most popular fully-featured backpacking packs on long-distance trails.

Osprey’s classic suspension system comes into play for bigger loads, and the ultra-padded hip belt and shoulder straps mold to your body for added comfort. The Aura comes in 65 and 50-liter options. The Atmos is the men’s version of this pack and also comes in 65 and 50-liter options.

Features

  • Front opening: The front opens vertically for easy access to the main compartment.
  • Pockets on pockets on pockets: A pack that weighs 4.5 pounds comes flush with pockets and organizational options.
  • Top lid: Two zippered pockets are ideal for stashing quick-access snacks and small items.
  • Anti-Gravity suspension: The mother of all comfort for heavier packs.

Nobody’s Perfect

This pack weighs 4.5 pounds empty, which is more than double the weight of the most popular ultralight packs. That’s the main thing working against it, but it makes sense considering the durable materials and feature-rich design. If you want a lightweight carrier, this is not the pack for you.

Granite Gear Crown3 60 Unisex | Women’s (Most Versatile Pack)

best backpacking backpacks

Best backpacking backpacks for thru-hiking: Granite Gear Crown3 60

  • MSRP: $260
  • Weight: 38 oz
  • Volume: 60L
  • Maximum load capacity: 25 – 43 pounds depending on frame configuration

Why We Love This Pack

At nearly 42 ounces, the Granite Gear Crown3 60 is hardly ultralight, but it does a great job of bridging the ever-widening divide between traditional, fully-featured load haulers like the 4.5-pound Osprey Aura/Atmos and the absurdly light 11-ounce Zpacks Super Nero. Its simple, straightforward design makes it intuitive for even a complete novice to backpacking.

Where the Crown shines is in its versatility. The top lid is removable, so you can leave it behind to save almost four ounces, BUT much more excitingly, you can also clip the brain to the sternum straps for an oversized chest pocket, or clip it to the removable hip belt to create a high-capacity waist pack for day hikes. The brain stuffed with extra clothes also makes an exceptional camp pillow, apropos of nothing. The plastic frame sheet can be removed to shave weight for ultralight loads or reinforced with an aluminum stay to turn it into a heavy-duty load hauler.

The Crown3 also accommodates a fairly broad range of sizes: both the women’s and unisex packs come in multiple torso lengths and feature Granite Gear’s exceptionally adjustable Re-Fit hip belt.

Features                     

  • Re-Fit hip belt: Hip belt is adjustable via a simple velcro closure between 26 and 42 inches on the unisex fit and 24 and 40 inches on the women’s fit.
  • Removable and reinforce-able frame: A removable frame is a nice feature that can add flexibility to a pack and give ultralight newbs a chance to dip their toes in the frameless backpacking pool. But the Crown3 stands out because not only is the frame removable, but you can also go in the opposite direction and beef it up with an extra aluminum stay (sold separately) if you anticipate hauling heavier loads.
  • Dual sternum straps: Another unique feature of this pack is that it has not one but two sternum straps, adding more stability and another chance to fine-tune the fit. The secondary strap also makes it possible to clip in the removable brain and wear it as a chest strap instead, providing easy access to a high-volume pocket without having to take your pack off. The dual sternum straps are removable, so you can remove one or both if they’re not useful for you.
  • Shock cord bottle holders: Both shoulder straps have a pair of shock cord loops that can be used to hold a small water bottle.

Nobody’s Perfect

You could view the Crown as a bridge between ultralight and fully featured, or as a jack of all trades and master of none. At 42 ounces it’s neither a tricked-out traditional pack nor a streamlined minimalist. The chest strap configuration is a great idea but can look a bit silly, which is admittedly an us problem. The back suspension system is not the most breathable.

Mountain Laurel Designs Prophet 48 (Best Frameless Backpacking Pack)

best backpacking backpacks

Best backpacking backpacks for thru-hiking: Mountain Laurel Designs Prophet.

MSRP: $245 – $325
Weight: 17 ounces
Volume: 32 + 16 liters
Maximum load capacity: Up to 25 pounds

Why We Love This Pack

Mountain Laurel Designs has gained steady popularity on long-distance trails over the past few years. Just be sure you’re ready to commit to a UL, frameless pack before taking the dive.

The hip belt provides ample cushion for a pack of this weight, and the generous pockets allow for external organization. The pack can hold a standard bear canister and has a roll-top closure with a Y-strap to secure gear on top of the pack. It sits close to your back for stability.

The pack is unisex, with curved shoulder straps that should fit comfortably on most men and women. There are enough sizing options that finding the right fit isn’t an issue. You can also size up to the Exodus or down to the Burn if you really want to dial the fit. The Prophet is available in both Ultra X and reinforced 200D coated nylon ripstop, with added reinforcement on high-abrasion areas.

Features

  • Side pockets: Pockets are deep and can hold water bottles as well as bladders.
  • Padded shoulder straps: For a UL pack, the Prophet has some seriously comfortable shoulder straps. Straps are three inches wide, made of SuperWick mesh lined with foam padding. “Love them, best of all my packs,” said gear reviewer Alexander “GPS” Brown of the shoulder straps.
  • Roll-top closure: A Y-strap cinches down over the top of the closure, compressing the load as it decreases between resupplies.
  • Hybrid design on external pockets: The classic large front and side pockets are durable ripstop with mesh corners for draining.

Nobody’s Perfect

We’ve noted this, but this pack is for ultralight hikers. Heavier pack loads won’t feel as supported. There’s a learning curve when it comes to frameless packs, so you should be an experienced backpacker (and/or willing to put in time and effort to learn how to use the Prophet) if you choose this pack.

Durston Gear Kakwa 40 (Most Capable Ultralight Pack / Best Value)

best backpacking backpacks

Best backpacking backpacks for thru-hiking: Durston Gear Kaka 40.

MSRP: $250
Weight: 27.3 ounces
Volume: 40 + 15 liters
Maximum load capacity: 45 pounds

Why We Love This Pack

The Kakwa might just be the most feature-rich ultralight pack available. Every stitch, pocket, and buckle has been carefully considered by designer Dan Durston to contribute to his vision of a backpack that makes few sacrifices. The result? An incredibly durable pack that can comfortably haul heavier-than-average loads and comes equipped with handy features such as shoulder pockets. Oh yeah, and it also weighs less than two pounds and is one of the cheaper picks on this list (especially if you go for the $190 UltraGrid version of the pack), hence the additional “Best Value” award.

Seriously, if you’re looking for an ultralight pack but aren’t ready to give up your load capacity by going frameless, then the Kakwa should be a serious consideration. Its versatility makes it a competent choice for going fast and light on the AT or for hauling huge water loads on the CDT.

And don’t be put off by the minimal 40-liter capacity. If you need more space, the Kakwa is also available in a 55-liter version. This is the same affordable, premium pack, just with more space.

Features

  • EPL 200 Ultra fabric: Colloquially known as Ultra 200, this 200-denier woven laminate is the next great thing in ultralight fabrics since Dyneema Composite Fabric (DCF/DCH). Ultra utilizes the same Dyneema unicorn hairs that make DCF super strong for the weight, weaving them with polyester for more puncture and abrasion resistance.
    • There is also a slightly heavier UltraGrid Kakwa: it costs less (just $190) and weighs about two ounces more.
  • U frame:  Made from a single aluminum tube bent into a shape that kind of resembles an inverted U, the Kakwa frame is the invisible hero of this pack. The horizontal crossbar provides another dimension of stiffness that is often lacking in ultralight backpacks, and allows the Kakwa to carry heavy loads more comfortably and resist barreling.
  • QuickPocket: A vertical zippered pocket integrated into the left side pocket offers secure storage for items that might be too large for the hip belt pockets. Think paper maps, gloves, beanie, snacks, or a large cell phone.
  • Shoulder strap pockets: Each shoulder strap rocks a stretchy, cinch-top pocket. Yet another option for keeping essentials and snacks within reach.
  • Load lifters: Adjustable straps connect the top of each shoulder strap with the pack’s frame. Often absent in ultralight packs, these little wonders help transfer weight off of the shoulders when the load gets heavy and can help dial in how snuggly the pack contacts one’s back.

Nobody’s Perfect

There’s not a lot to nitpick about the Kakwa, but hikers who love a cavernously stretchy outer mesh pocket might find the no-stretch Kakwa mesh (chosen for durability) a little restricting. And call us greedy, but more color options wouldn’t be a bad thing in our opinion, just sayin’.

Hyperlite Mountain Gear Southwest 40 (Best Water-Resistant Pack)

Best backpacking backpacks for thru-hiking: Hyperlite Mountain Gear Southwest.

MSRP: $349-$369
Weight: 30 or 32.4 ounces
Volume: 40 + 10 liters
Maximum load capacity: 40 pounds

Why We Love This Pack

Hyperlite Mountain Gear has perfected the art of the no-frills, ultralight, rugged backpack. Based on the miracle fabric known as Dyneema Composite Hybrid (DCH), HMG harnesses the minimalist ethos with a pack that is essentially a large tube accompanied by a few extra pockets. The result is a lightweight pack that, through simplicity and intelligent material choices, can handle just about everything.

The DCH is not only ready for bushwacks and rocky scrambles, but it is also fully waterproof when new. Combined with the roll-top closure, this tandem results in a pack that is at home in soggy conditions and desert grit.

But don’t let the simplicity and low weight fool you. HMG’s packs are also capable load haulers. They are also available in a few different versions and capacities to suit different environments. The Southwest, with its solid fabric outer pockets, is available in  40-, 55-, and 70-liter versions. So are the HMG Windrider and Junction, which are based on the same general design, but use different outer pocket fabrics.

Features

  • DCH material: Super strong and super lightweight, DCH is also waterproof and durable, making it a great pack material. Woven polyester face fabric improves puncture and abrasion resistance over DCF, so this pack is ready to be tossed around. HMG offers the Southwest in two DCH options, white DCH50 and black DCH150, which is heavier duty.
  • Solid external pockets: The most durable of HMG’s pocket materials, hardline is made with Dyneema fibers to withstand abrasion from grit and rocks. It is also a solid fabric, so it’s less likely to get caught on branches during bushwacks.
  • 2 aluminum stays: This simple design is lightweight yet effective. Two vertical stays help transfer weight to the hip belt, topping out at 40 pounds. They are also easily removable for lighter trips.
  • Roll-top closure: This simple closure system is great for a lot of reasons, including simplicity and weather-proofness. Like a drybag, it’s good at keeping stuff out and also keeps the pack tidy as pack volume fluctuates trip-to-trip, section-to-section.

Nobody’s Perfect

Dyneema has always demanded a premium price, and HMG’s packs have always been some of the most expensive UL options available, especially considering that other packs include other coveted features like shoulder pockets. Budget-conscious hikers might want to look for a different fabric, which means no HMG. And speaking of features, HMG packs are noticeably devoid of bells and whistles (OK, they do include a whistle). For backpackers who like a lot of pockets and storage options, these are not the packs for you.

ZPacks Arc Haul Ultra (Best Ultralight Suspension System)

Best backpacking backpacks for thru-hiking: Zpacks Arc Haul Ultra.

MSRP: $399
Weight: 21.4 ounces
Volume: 47 + 13 liters
Maximum load capacity: 40 pounds

Why We Love This Pack

Zpacks replaced the old gridstop Arc Haul with the more durable, slightly lighter Arc Haul Ultra in 2022. Ultralight stays provide stable weight transfer from shoulders to hips, while the Lycra back panel keeps the pack suspended off your back for airflow — much needed during hot or humid hikes.

The pack doesn’t have hip belt pockets (boo!) but can be customized with optional add-ons like a hip belt pouch or fanny pack. The removable hip belt is dual-adjustable, and the torso length can be dialed in too. Like all good UL packs, the Arc Haul Ultra features a stretchy mesh back pocket for stashing wet or quick-access gear.

Zpacks’ suspension system continues to impress. The Arc Haul Ultra carries weight extremely well for something so light: 40 pounds of carrying capacity in a scant 22-ounce package is hard to argue with. One of our contributors pointed out that a pack with 60 liters and 40 pounds of capacity isn’t necessarily in the “ultralight” spirit, but we couldn’t fit “Best Pack for Non-Minimalists Who Like a Few Luxuries and/or Need a Bear Can but Still Want a Sub-Two-Pound Pack” on one line.

Features

  • Absorbent, padded straps: The multilayer mesh on the shoulder straps and hip belt are cushy and absorb sweat while helping keep you cool.
  • Roll-top closure and seam-sealing: This bag is highly water-resistant, with taped seams and a waterproof coating on the inside of the material. The roll-top closure lets you shrink your pack as your load lightens between resupplies.
  • Fits all standard bear canisters: The Arc Haul Ultra will fit all standard bear canisters, as long as you stand it on its end in the upper half of the pack. This includes the BV500, which did not fit in previous versions of the Arc Haul.
  • Angled side pockets: Durable side pockets fit several liters of water and are angled to help you grab bottles on the go.

Nobody’s Perfect

We like hip belt pockets, and you’ll have to buy those separately with the Arc Haul Ultra (which is already pretty dang expensive to begin with). More than other brands, Zpacks gets knocked for a lack of durability and quality control, with repairs on the suspension being an often-reported issue.

Gossamer Gear G4-20 (Best Budget Ultralight Pack)

best backpacking backpacks thru-hiking

Best backpacking backpacks for thru-hiking: Gossamer Gear G4-20

MSRP: $205
Weight: 24.8 ounces
Volume: 30 + 12 liters
Maximum load capacity: 30 pounds

Why We Love This Pack

Gossamer Gear’s G4-20 cuts out the weight of a frame while remaining comfortable with loads of up to 30 pounds. The foam back panel doubles as a removable sit pad and does a surprisingly good job of transferring weight to the hips via a cushy hip belt. Meanwhile, Gossamer Gear’s classic, wide, thickly cushioned shoulder straps also do a great job of distributing what burden is left for the shoulders.

It’s the simple, minimalist design that makes it an awesome pack — no lids or sleeping bag pockets on this thing. The roll-top closure and side compression cord keep it sleek as food stores dwindle, and the combination of a rear mesh stuff pocket and two exterior side pockets provide ample storage for quick-access items. One exception to the minimalist ethos is the zippered pocket above the rear mesh that is perfect for securing important items like a headlamp, wallet, or keys. There are lighter packs out there, but the G4-20 strikes the right balance of comfort, features, and low weight.

The latest update of the pack features new colorways and a switch to PFAS-free recycled Robic nylon.

Features

  • Frameless: The foam back panel / sit pad does a decent job of transferring loads to the hips, but excess weight should be avoided. Gossamer Gear rates the G4-20 fit to carry 30 pounds maximum, or 25 pounds for comfort.
  • Roll-top: This is great for compressing bulky gear or shrinking the pack as food is consumed.
  • Zipper pocket: This outside pocket provides secure storage for important, on-hand items. If you’re nervous about ditching a pack lid, this is a great compromise.
  • Asymmetrical side pockets: One side is taller, one is shorter. Both hold two Smartwater bottles securely while maintaining pack-on access.
  • Removable sit pad: The foam back panel is also a sit pad that keeps your butt comfy during breaks. Gossamer Gear offers other versions, or you can make your own.
  • Sizing: The G4-20 comes in three non-adjustable torso lengths with a fixed hip belt.

Nobody’s Perfect

The one potentially major issue involves the hip belt, which is fixed and cannot be exchanged for a different size. A hiker’s torso length is a poor predictor of their waist measurement, and the G4-20 hip belt sizing excludes skinny hikers with a medium or long torso. On a thru-hike, a 30-inch minimum waist for a medium pack (32-inch minimum in size large) might not be tight enough to account for weight loss. There are inventive ways to add padding to get around this, but starting with a smaller hip belt is the best option.

It is also important to note that the comfort of the G4-20, and frameless packs in general, is highly dependent on not just how much is being carried, but also how it is packed. A little practice is needed to find the most comfortable configuration.

Atom Packs Prospector (Best Customizable Backpacking Backpack)

best backpacking packs for thru-hiking

Best backpacking packs for thru-hiking: Atom Packs Prospector

MSRP: $327+ (40L size)
Weight: 30.7 oz*
Volume: 40, 50, or 60L
Maximum load capacity: 42 pounds

*base model

Why We Love This Pack

Formerly called the Mo, this sharp-looking backpack has been growing in popularity for years, and commenters have been threatening to revolt if we didn’t add it to our top picks. This is far from the only made-to-order backpacking pack on the market, but the sheer number of custom features offered by UK-based Atom Packs sets the Prospector apart from the competition. You can even add a custom avocado pocket! On the left OR the right side.

The pack basically weighs two pounds plus or minus a few ounces depending on the size and features you pick. With a 42-pound max load out and enough space to fit a large bear can, the Prospector is a sensible choice for weight-conscious thru-hikers on even the longest and most rugged trails. Our tester found the pack extremely comfortable even under a substantial load, thanks to the weight distribution and well-placed lumbar pad — and this testimony seems to jibe with feedback we’ve heard from other hikers.

Also, the pockets. We love having more options than less: not just optional hip belt pockets, but also your choice of a bottom sleeve and even shoulder strap pockets (and the aforementioned whimsical avocado pocket. Did we mention the avocado pocket?). The water bottle pockets have 2.5L of capacity apiece and are easy to access.

Features

  • Removable hip belt: The hip belt features dual-adjustable webbing straps so you can dial in the fit to perfectly hug your hips and, like the Durston Kakwa, the straps tension by pulling in toward the middle rather than out away from your body. Pockets are available as optional add-ons. The belt can also be removed altogether to save about two extra ounces.
  • Lumbar pad: A combination EVA foam and spacer mesh lumbar pad provides extra cushioning and support against the small of your back.
  • S-shaped shoulder straps: S-straps are more ergonomic than traditional J-straps overall. Atom Packs also integrates load lifters to aid with weight distribution.
  • Removable back panel: The foam back panel provides a little extra cushioning, but you can also pull it out to save almost an ounce
  • Ecopak EPX200: The main body is made with Ecopak, a waterproof UL fabric that’s a little cheaper and a little heavier than Ultra.

Nobody’s Perfect

US customers: this pack is shipping from the UK and shipping is not free, so be sure to factor that into your budget calculations. We’d love to see an Ultra version of the pack introduced at some point. Also, it’s not seam taped, unlike the LiteAF Curve (what we would call the Prospector’s top competitor in the custom backpack space).

Six Moon Designs Swift V (Best Pack for Back Injuries)

Best backpacking backpacks for thru-hiking: Six Moon Designs Swift V.

MSRP: $250-$275
Weight: 36 ounces
Volume: 41 + 15 liters
Maximum load capacity: Up to 35 pounds (25 pounds in frameless mode)

Why We Love This Pack

The Swift V is based on 2020’s Six Moon Designs Swift X pack, but it’s cheaper and somewhat lighter. It’s a pretty standard roll-top, midweight pack, with the standout feature being its optional vest yoke. The pack uses a dynamic six-point connection system to attach the vest to the pack. The top of each side is connected to the top of the pack in a standard configuration, but the bottoms are free to move on an adjustable piece of webbing. This means that the pack is able to shift to conform to your body as your pack weight leans back and forth as you hike, making for more consistent dispersion of the weight.

The vest is super comfortable, evenly dispersing weight across the torso. It’s a great choice if you have back problems, but also for anyone who values comfort in general. As a bonus, the vest’s ample surface area means lots of room for pockets. SMD managed to fit three fully functional pockets on each side of the vest, making for six pockets right there in your peripherals.

The pack was updated in 2022 with deeper interior pockets, two additional side straps, and Ultra Stretch pockets. The Swift isn’t the lightest pack around, but effective load transfer and weight distribution helps to offset the extra ounces. And if you’re ultralight in the rest of your gear, you can opt to remove the Delrin stay, shaving three ounces from the pack’s total weight.

Features

  • The vest: This is the defining feature of the pack, hands down. The company’s founder designed the pack to be able to hike more comfortably after a bout with cancer, and that comfort is top-notch. This pack has a unique carry that really is something special. While a few other packs feature running vest harnesses, most are geared toward the fastpacking crowd. The Swift V, in contrast,
  • The pockets: Technically part of the vest, these pockets make the organization of snacks, headphones, cameras, and trail trash a real breeze.
  • A REAL optional hip belt: The removable hip belt on the pack is as good as the hip belt on pretty much any other pack of a similar size. There is a normal pocket on each side, the adjustment straps are easy to use and functional, and the internal frame configuration legitimately works and transfers weight.
  • Removable frame: The pack features a Delrin hoop stay, which can be removed to shave three ounces from the pack’s weight. Just note that the overall carrying capacity is reduced by about 10 pounds without it. It’s rare to see a frameless pack with an adjustable torso length, another feature that makes the Swift V stand out from the crowd.

Nobody’s Perfect

The Flight vest harness (by far the standout feature of the pack) is not standard issue. To use this pack optimally, it’ll cost you an extra $25. The nylon fabric used in this pack is

Nashville Cutaway (Best Fast and Light Pack)

Best backpacking backpacks for thru-hiking: Nashville Cutaway.

MSRP: $346*
Weight:
15.8 oz
Volume:
34 + 10.5 liters (also 25 + 8 and 43 + 12)
Maximum load capacity:
25 pounds (per manufacturer)

*Price and weight are based on 18″ Ultragrid pack + 17.5″ shoulder straps. Doesn’t include accessories such as sternum strap, one-inch hipbelt, or side compression straps (which can be purchased a la carte). You can get a stock Cutaway made with EPX70 for about $20 less, which is the way to go if you don’t care about customizing the fabric and colors.

Why We Love This Pack

The Cutaway is by far the most recommended running-vest-style pack for hikers looking to travel fast and light. At 15 ounces (admittedly that’s not counting any accessories you may choose to add, such as a sternum strap or side compression straps), it’s the lightest backpack on this list.

The compact, frameless design is such that you should be able to fully access any external pocket on the pack while wearing it, while the shoulder harness disperses weight across the chest and keeps the pack snug when moving at speed. Shoulder strap water bottle pockets make hydration easy.

The default Cutaway uses EPX70 for the fabric, but you can get a pack made to order with custom colors and your choice of EPX200, Ultra 100X or 200X, Ultragrid or Aluula Graflyte. A variety of add-ons, like ice-axe loops and a 1″ webbing hipbelt, are also available.

Features

  • US-made: Nashville packs are handmade in Tennessee.
  • Still keeps the classics: Traditional features like the roll-top closure with opposing buckles and classic mesh stow pocket on the front keep this pack feeling familiar.
  • Pockets for days: Six pockets on the shoulder strap provide easy access to drinks, snacks, and smaller essentials.
  • Bottom pocket: Stretchy pocket sewn along the bottom of the pack is easy to reach.

Nobody’s Perfect

As with most cottage manufacturers, future Cutaway owners have to contend with long wait times for custom packs. This is not a last-minute purchase. With a 25-pound recommended load limit, this pack is best for true minimalists. If you have older or bulkier gear (or you can’t leave the luxury items at home), this is not the pack for you.

Zpacks Super Nero (Lightest Backpacking Pack)

best backpacking backpacks thru-hiking

Best backpacking backpacks for thru-hiking: Zpacks Super Nero

  • MSRP: $269
  • Weight: 12.1 oz
  • Volume: 50L
  • Maximum load capacity: 20 pounds

Why We Love This Pack

I mean, how can you not love the idea of a 12-ounce, 50-liter backpack? That’s just wild. Do note that this weight is with standard straps and no hip belt. The weight can go as high as 19 ounces if you choose a large padded hip belt and vest-style shoulder straps.

But considering that this pack has a max recommended load of just 20 pounds and is meant for true UL hikers, you probably don’t even need a hip belt anyway. And the vest straps are purely a matter of personal preference: you might love the idea of a more distributed harness system (to say nothing of those shoulder strap pockets!) and consider the four-ounce weight penalty worth it.

Point is, in its lightest configuration, you won’t find another similarly sized pack as light as this. Our reviewer, Alex, sums it up best: “the Super Nero is an absurdly light pack that makes a few compromises on comfort and long-term durability to achieve its feather-light weight. It exists to cut base weights by any means and is best for experienced, ultralight-focused hikers.”

Features

  • Interchangeable shoulder straps: Choose between standard 3-inch wide S-straps (2.5-inch wide for the small/women’s straps) or a vest-style harness for an extra $50. The vest straps also come with pockets.
  • Frameless: Zpacks foregoes the frame in this superlight pack to keep the weight as low as possible.
  • Seam taped: You should probably still use a pack liner, but the fact that the seams are taped dramatically improves this pack’s water resistance (it’s made with waterproof Utra 100x to begin with). Also, seam taping improves the strength of the seams, boosting durability.
  • Adjustable torso: The hip belt can be moved up or down between three positions to adjust the torso length (assuming you’re using the hip belt). Can be adjusted between 18 and 22 inches (a suitabe range most adults, but won’t fit people on either end of the torso length spectrum).
  • Comes with foam sit pad: 1-ounce closed-cell foam sit pad (11″ x 15.5″) provides extra back cushioning and support. Held in pace with shock cord.

Nobody’s Perfect

Alex tested both shoulder strap styles and found both quite uncomfortable with minimal useable padding. We would also love to see the size range expanded over time: the 18 to 22-inch torso length limit will exclude shorter and taller hikers, while the lack of a small padded hip belt option makes this pack less functional for lean builds.

Symbiosis Aspen (Best Women’s Ultralight Backpack)

best backpacking backpacks for thru-hiking

Best backpacking backpacks for thru-hiking: Symbiosis Aspen

  • MSRP: $299
  • Weight: 25 oz
  • Volume: 38L
  • Maximum load capacity: 20 pounds

Symbiosis Gear describes the Aspen as “the backpack for people with boobs.” This isn’t the only backpack designed specifically with female bodies in mind, but it is pretty much the only true ultralight women’s pack. The Osprey Eja is a great female-specific pack, for instance, but it weighs almost three pounds. The Aspen weighs barely more than 1.5.

The S-curve shoulder straps paired with a three-way-adjustable, elasticized sternum strap, make it easier to dial in the fit through the chest area regardless of your body type. The Aspen was created by a woman — Mellow, the owner and founder of Symbiosis — after struggling to find a pack that fit her properly on the PCT.                  

Beyond the boob-friendly fit, it’s just a solid backpack overall. It’s frameless, so it will work best for hikers with a true ultralight setup. Special pockets always make us happy, and the Aspen delivers with an easy-to-access bottom pocket and shoulder strap pocket for your phone. 38 liters should be enough capacity for most UL hikers, but an extra-long Y-strap on top will come in handy for strapping down extra gear if needed.

Features

  • Stretchy sternum strap: Contours to a wide variety of body types without constricting your chest. You can adjust where the strap sits on your chest via a daisy chain attachment system.
  • Spacer mesh on back panel to improve airflow: Reviewer Ariella notes that the pack features more cushioning in the back panel and shoulder straps than other ultralight packs she’s tried.
  • Stowable webbing waist belt: The 1.5″ webbing waist belt is non-load-bearing and can be stowed out of the way inside the side water bottle pockets when you don’t want to use it. It fits up to 50″.
  • 420d Extreema: The majority of the pack is made with 420d Extreema, a highly durable, abrasion-resistant, and water-resistant reinforced Robic nylon.                

Nobody’s Perfect

Like all frameless packs, your carrying capacity will be limited to about 20 pounds with the Aspen (our reviewer pushed it to about 25 without issue). The phone pocket is very convenient, but loose enough on top that the contents of the pocket could spill on a technical trail that involves a lot of scrambling.

The Best Backpacks for Thru-Hiking: FAQs

What Capacity Do You Need?

This depends on what you’re doing. If you just have one pack for all your outings, a 50L pack (or thereabouts) is the safest option. 50-55 liters will carry everything you need for the majority of treks and between most resupplies while preventing you from overpacking. A smaller pack (35- 45-liter range) is only smart for experienced long-distance backpackers with ultralight setups. If you pack heavier items, or your trail requires longer water carries, time between resupplies, or extra gear, look for something in the 60- 65-liter range.

One of our spec categories is “maximum load capacity,” but keep in mind that we’ve found manufacturers tend to be a bit generous when listing maximum weight capacity for their packs. Err on the side of caution when loading the bag. If our reviewers recommend a weight, it means they’ve personally tested it and can attest to the load limit. But again … these are not scientific load recommendations.

Per conventional wisdom, your backpack should be the last piece of gear you buy. That way you can size the volume of your gear and you’ll know for sure what size of pack you need.

What are the most important features to look for in the best backpacks for thru-hiking?

maggie slepian backpacking hyperlite mountain gear

I realize I do not know how to have my picture taken. Now that we’re clear on that, the HMG 3400 Southwest has some great features (large hip belt pockets, deep front pocket), but I miss having a top lid, and I had to get my shoulder pocket separately. When you choose a lighter pack, you lose some features.

It depends on how much on-the-go convenience you want. Here are a few features (mostly pockets, let’s be real) to look for when you choose a pack.

Brain: Brains (or “top lids”) have more space than hip belt pockets and more protection than front mesh pockets. They’re a great addition for mid-size items you don’t want to get lost in your pack. When I went to a more lightweight pack, I definitely missed the top lid. Many brains are removable with zippered pockets on the top and bottom.

Hip belt: A hip belt is a must for many hikers. It offers support and weight distribution, especially critical if you are carrying a heavier load. Look for a padded hip belt with easily adjustable buckles. You’ll probably go down a size or two on a thru-hike, and if the belt doesn’t cinch all the way down, it won’t offer enough weight distribution to make it worthwhile. Pockets on the hip belt are clutch, perfect for a headlamp, small water filter, and snacks. Some ultralight hikers opt-out and use fanny packs, which they can around town to keep valuables close.

READ NEXT — The Best Fanny Packs for Thru-Hiking

Sternum strap: Another way to keep your pack load close to your body and relieve pressure off your shoulders. This is easily adjustable and should sit flat under your collarbone. The Six Moon Designs Swift X has two sternum straps, which provide double the surface area for weight distribution. Our tester also said they reduced chafing.

Load lifters: These are important for heavier loads and are often found on mid-range and fully-featured packs. They attach to the pack body (or frame, like the Zpacks Arc Haul) and shoulder straps, and can tighten to secure the pack load closer to your body, which reduces direct loading on the tops of your shoulders. Release the load lifters to counterbalance a steep descent. Tighten them against your body for steep climbs to keep the weight close.

Side pockets: These are where your water bottles go. If you like to be able to reach your water bottles while walking, look for side pockets with an angled cut so you can grab them and put them back without asking for help. The material should be stretchy but durable, and comfortably fit at least a one-liter bottle of water. Also, they should be tall enough that a water bottle won’t fall out.

Shoulder pockets: Shoulder-strap pockets are great. It’s kind of a bummer that they aren’t on more packs these days. Do I sound old? I loved the stretchy mesh pockets on my 2015 Exos. I kept my phone in there for quick access for pictures, and also gummy worms. You can buy shoulder pockets separately from a few different companies (I have this one from Hyperlite) but they can be clunky.

Fully Featured, Ultralight, or Somewhere in Between?

maggie slepian jeff garmire backpacking

Sometimes even ultralight hikers carry a full load. This Elemental Horizons Kalais XT is packed with fishing gear, a six-pack, and a jar of salsa.

This depends on your packing style. People with a sub-10-pound base weight can confidently carry a frameless pack. But if you’re hitting a trail with long water carries, remember that water weighs two pounds per liter, and will bring up your total weight.

Lay out your gear. Now weigh it. Do you carry over 20 pounds as a base weight? You’ll need a burlier pack like the Osprey Atmos or Gregory Deva. Ten- to 15-pound base weight? A mid-weight pack like the Gossamer Gear Mariposa or Granite Gear Crown3 will work swell. Less than a ten-pound base weight? You’re a candidate for a smaller capacity, frameless pack like a Pa’lante Pack or ULA CDT.

We’ve written at length about the temptation of going ultralight. But if your hiking style and pack load aren’t conducive to a 35-liter frameless pack with no hip belt, you’ll be ditching it at the next road crossing and hitching a ride to the nearest gear shop. That said, the weight of a 70-liter, fully padded pack can be six pounds or more empty. While these are the best backpacking backpacks for carrying heavy loads, many thru-hikers ditch enough gear within the first few hundred miles to not warrant the extra suspension and padding.

Midweight models like the Mariposa, Exos, or Swift X have enough features and suspension to carry around 30-35 pounds comfortably, but without the beefy buckles, memory foam hip belts, and enormous capacity to bring your base weight too high for happiness.

PSA: Packs Come in Different Torso Sizes

I mistakenly ordered a size small Gossamer Gear G4-20 (left). The torso was a few inches too short, making the hip belt float around my waist like a technical tutu. I exchanged it for a medium (right), which fits well. You can see the shoulder straps extending straight back, and the hip belt sitting, well, on my hips.

A pack is something you wear, therefore they come in different sizes. This may sound obvious, but it came as a surprise to me when I bought my first backpacking pack (and apparently I still can’t figure it out). Your shoulder straps should extend straight out from your shoulders, not drop down (torso too short) or extend up (torso too long). Having the wrong size pack means the pack won’t distribute the weight as it was designed to. You will feel fatigue in your shoulders as it pulls back, while not sitting correctly on your hips.

Also! Don’t assume that because you’re a certain size in one brand, you’re that size all around. I am a Small in Hyperlite Mountain Gear and ULA, but a Medium in Gossamer Gear, and I blew it by ordering my G4-20 in a small. If you can, it’s always better to try the pack on. If you can’t try it on, most companies have reference pages where you can measure your torso and know what size to order, along with instructions for measuring your torso to their specifications.

    I can’t believe that this review did not include the most versatile, midweight pack on the market: the Granite Gear Blaze A.C.60. For women like myself that have extremely short torsos (14.5″) there are almost NO PACKS that will fit me. But the Blaze A.C.60 not only fits me, but at less than three pounds has a fully functional frame and suspension system and user friendly pockets and compression system.

    On the Exos 48. I just bought one. And you know those tight side pockets you talk about? Those are perfect! This is the first pack that I (with my mangoed shoulders due to a past life of motorcycle racing) can get my water bottle in and out while wearing the pack. And I can put my snacks and such in those side pockets (that I put in the hipbelt pockets that I have on my other packs and that they took away on the Exos. I wouldn’t trust them with my phone but I plan to use it for my bear spray as well. Love the pack. Great southeast summer pack (hot and humid) due to the awesome aeration on the back (primary reason I bought it). In other words, all those who moan about the hipbelt pockets, they just relocated it by tightening up the mesh on the side pockets. I have only put 40 miles on it so far, small things are staying in it for me.

    Did you all check out the Seek Outside Flight? I think it’s a better option than the Osprey Aura/Atmos for heavier loads– and it’s half the weight. It’s also most excellent for anyone with shoulder problems who needs more weight going to the hipbelt than most UL hikers.

    I feel like the tent and backpack “best of” articles have been recycled for the past few years, with only minor tweaks. Maybe because things haven’t changed that much, or certain brands haven’t gained as much traction as some readers would like. This is supposedly based on surveys of thru hikers of the big three trails, or so we think… Hopefully the writer/editor isn’t being journalistically lazy and just reposting an old article and is actually making sure it’s up to date in all realms of current trends.

    Sorry to burst some commenters’ bubbles, but those budget friendly weigh-a-ton Ozark Trail packs and those lesser known European or mom & pop brands aren’t always going to make the top three list…because not enough thru hikers use them for thru hiking. (pick a reason…price, weight, availability)

    I’ve got a few packs mentioned here and in comments… ULA, LiteAF, SeekOutside, Volpi, GossamerGear, DurstonGear, a few army russacks, some random packs from Bass Pro & Walmart, and even an old Kelty (which I gave to a friend). They all have their pro’s & con’s and all serve their own purpose. I’d choose my Circuit, Curve 40L or Kakwa 40 for overnight hikes, and my Catalyst or Unaweep 4800 for winter trips.

    I have an older model Exos 58. Great bag. Love the back meshing and the overall comfort. I’m taking it on my AT thru-hike this year.

    That said, I’m very confused about the comment about the Exos’ hip pockets. Osprey updated the Exos last year (2022) and it has hip pockets now. If you follow the link to REI in the section about the Exos you can see the model using them in some of the photos.

    • DAVID FIRARI : Jan 16th

      I think I understand my confusion better now. There’s a footnote at the bottom of this article that this is an update to an original article. My guess is the paragraph about the Exos missing its hip pockets was overlooked during the update.

      This also explains why the 2023 list “posted” in January already has comments from February and March. Its because it’s the same article as last year, just updated. The comments are from older iterations of this article.

      I understand the ease of updating a large article instead of starting from scratch, but I wish that information that is repeated from the prior update is vetted for accuracy before being posted again.

    Great article! We all have different preferences. I’m currently really happy with my frameless Volpi UL40 for shorter/summer trips – if I ever get serious about cutting luxuries it’ll work for a thru hike – and my Granite Gear Crown 60 for trips where I want to carry more voluminous gear. I’m awaiting delivery of Durston’s new Kakwa 55L pack, which may replace my Granite Gear pack as it promises lighter weight, more features, and waterproof material.

      I may have missed it, but where does the article mention ‘fit’.

      All the packs have pros/cons supporters/retractors, etc; but all of the choices will only work if the require hiker gets a pack that is the correct measurement for their torso

      I had a incorrectly fitting pack for a 600mile hike and vowed to spend the time understanding and getting a fitted pack. I got one for the AT (it is in the list) that was properly measured to my body. There were days when I forgot I even had a pack on

    Maybe someone here can clear up something that’s been confusing me. I frequently see comments on how “spacious” the ULA Circuit is (this article included). But when I look at the actual specs of the pack, it’s the same internal 40L as half the other packs on this list. So how come on the Circuit it’s “one of the roomiest packs you can get”, while on something like the Kakwa we’re cautioned to not be “put off by the minimal 40-liter capacity”. And yes, I get that there’s an external capacity component here, but I (and I expect most others) don’t count external volume the same way we do internal volume due to how we load the pack (ie it doesn’t really matter how deep the side pockets are to me, they’re still just going to be holding mostly smart water bottles).

      I am not familiar with all the backpacks mention. I have been using my Mariposa for almost four years. I use the large side pocket for my tent and stakes. The bottom smaller external side pocket is where I carry my cook system the top external side pocket is where I carry my potty bag and camp gloves. Also, there is a zippered pocket on the very top that I carry my spoon and my water filter and CNoc bag. The back mesh pocket is where I carry rain gear, sit pad, camp shoes and extra water bottle I fill and use for camp. Just saying that the external pockets are an intricate part of the overall capacity for me.

    I, too, am surprised by the lack of AtomPacks. Although I don’t doubt your research is high quality, and much of my research is based on The Trek, you can’t go five minutes of backpack searching without AtomPacks being hailed as one of the absolute best, with only cost or lead time being noted as a barrier to ownership. I’ll be going for a Mo Custom for the AT next year and have the great joy of being able to get it made in the colours of the charity I’ll be raising money for. I know another hiker going out to start the AT in less than two weeks who has a Mo as well, and we’d both come to the decision of that pack totally independently, I only found out when he shared his lighterpack.com link!
