Gear Review: Patagonia Nano Puff Jacket

In 2015 I bought a puffy for a hike on the Colorado Trail that weighed in at 12 ounces at the time of this writing. It’s a great piece, still going strong (though marred slightly by a few grease stains and pinpricks from errant embers). But it’s definitely no-frills, sporting just one small exterior breast pocket, snaps instead of a zipper, a design that admits jabs of chilly air from time to time, and no drawcord to cinch up the hem.

Fast forward to 2020 and the latest iteration of Patagonia’s Nano Puff jacket. Weighing less than an ounce more (company specs say it weighs 11.9 ounces, but my scale read 12.7), it features two roomy, zippered hand pockets, a zippered interior breast pocket, a center zipper with interior storm flap and a drawcord to snug you up on a windy or chilly day.

What’s more, the exterior materials are 100 percent recycled, while the insulation is 55 percent postconsumer recycled content, and the PrimaLoft® fill retains insulating properties when wet.

Circumstance of Use

Welcome to the wonderful world of pandemic gear reviewing, in which one’s living room, backyard, and short, local expeditions must step up as understudies to the usual rigors of overnight camping and longer trips. I’ve worn the Nano Puff a lot since receiving it, not just indoors, but also on mornings where the mercury registered in the mid-40s Fahrenheit and the wind was blowing at 15 or 20 knots and in a modest rainstorm, and I’m confident that it will perform well in more extreme conditions.

It doesn’t pack as tightly as a down jacket, but is surprisingly compact. But the advantage of PrimaLoft® and other similar synthetics over down is considerable: it retains insulating power even when wet (and requires the sacrifice of no birds).

Patagonia Nano Puff Features

The pockets are lovely, dark and deep (apologies to Robert Frost).

Pockets: For me, this is almost the biggest step forward from my beloved older jacket. Having hand pockets just gives me so many more options for stashing a tube of lip balm or a bar, and the chest pocket is also roomy.

Cuffs: Elastic, non-adjustable. As happens with nearly every jacket I’ve owned, the cuffs do absorb rain and arm sweat.

Hem: Drawcord cinches up easily at a single interior point.

Zipper: Buttons have their benefits—sometimes I like to toss on my old jacket for the simple pleasure of tugging on the collar and popping them all open, prrrrrrp!—but on the whole, you’re better protected by a zipper. This one is easy to grab, featuring what I call a “glove cord” for those cold days. Evidently the small pocket at the chin meant to house the zipper is a “garage.” Good to know. Also, good feature, as it keeps metal from contacting the underside of your chin.

Collar: No hood, but a sturdy 2.5-inch collar—tall enough to kiss a tugged-down beanie.

Fabric: The 1.4-ounce 20-denier polyester is heftier than many ultralight jackets—twice as thick as my old jacket—which should give it more durability. The lining is 1.3-ounce 22-denier, which is even sturdier.

Storage: I was deeply skeptical that I’d be able to stuff the Nano Puff into the chest pocket, but turned it into a neat 10x6x3 bundle with a minimum of effort. Not bad at all, considering all the features and weather-resisting power it’s got. That said, it’s probably not advisable to store it this way for too long.

Colors: Quick rant about the usual color choices for men in outdoor gear: When are we, as a society, going to evolve beyond the idiocy that dictates men are only “supposed” to wear “manly” (i.e. dull) colors–Navy, black, gray, brown, maybe a deep forest green, or perhaps  maroon, for guys who really want to push the boundaries of color-coded masculinity? But Patagonia is cool, and thinks we fellas are secure enough to offer not just black, gray, Navy and brown, but also red, aqua, orange and light green. A veritable rainbow. Kudos.

About the Company

Patagonia is known for making actual investments for the future of the planet, including its self-imposed, 1-percent “Earth tax” to fund environmental nonprofits, concerted efforts to use postconsumer materials and support of activist movements. The Nano Puff is made in Vietnam.

Comfort and Sizing

I requested a medium, knowing that it might be a tad large for me, as indeed it is. At 5’7” and 140, I can often wear small men’s gear, but I’m OK with a little roomier jacket in case I’m layering up underneath (and I think Patagonia’s sizing is pretty standard). The Nano Puff fits nicely underneath my Mont-Bell rain shell, which also happens to be Navy.

Water Resistance / Insulating Power

I’m of the opinion that no jacket, no matter how high-tech or expensive, will keep you dry in an insistent downpour, or a mild one that lasts hours. And nobody in their right mind expects a puffy jacket to capably perform as a rain shell. That said, the Nano Puff features a DWR finish, inside and out, and raindrops beaded up nicely for a little while when I took it out in a modest rain. But who cares, right? The primary reason to go with a synthetic fiber like PrimaLoft® is the fact that it retains insulating power even when wet.

Although I have not had a chance to use the Nano Puff in temperatures lower than 45 degrees, it’s been plenty warm so far, and unquestionably warmer than my old jacket. It nicely fends off the prying fingers of wind.


  • PrimaLoft® retains insulating properties when wet
  • Lightweight
  • Tough material resists tearing
  • Three big pockets
  • Mostly recycled materials
  • Sweet color selection

The Nano Puff is compact enough not to feel bulky under a rain shell.


  • Cuff material sponges up arm sweat and rain
  • Not as compact as down-filled jacket
  • Might be nice to have a hooded option

I’m genuinely excited to put the Nano Puff through some more challenging paces when the time comes. For under $200 (what will you do with that extra dollar, hmmm?), a puffy with all these features seems like a steal, particularly given that the tougher fabric is likely to keep it usable for a long time. But don’t worry, my beloved (competitor name redacted) puffy, I still love you, too.

    I live in Ventura, and have a collection of Patagonia jackets. I have an older Nano puff that I like for light hikes, when it gets warmer. But my recent favorite is the micro puff (with and without hoodie) — a little warmers, stuffs better into things, and the pockets on the insides I love. Great review!

  • Kathryn : Dec 20th

    I’m very curious. Why night it be nice to have a good option? I just purchased one with a good snd keep wondering if I should have gotten the one without one. Thanks so much for your time !!

      Hi, Kathryn (or ‘bot, as the case may be….)

      I think you are asking whether a hood would be a nice option.

      Answer: Sure, if you want a hood.

      • Kathryn : Dec 25th

        Wow I had a lot of typos. I’m going to blame that on the lack of sleep with my 6 month old! Not a bot. Just a mom whose getting back into hiking with my kiddos. I purchased the nano puff with a hood and my husband got one without. I keep going back and forth about getting one without and was curious why you listed it as a con. Thanks so much for your time!!
