For every moment of an alpine mission, the Nano-Air® delivers a breakthrough in active insulation. Put it on and leave it on through high-output, stop-and-go cold-weather adventures—its stretchy and highly breathable fabric package integrates the qualities of fleece, soft shell and puffy by combining our warm-when-wet FullRange® insulation with a plain-weave liner and a lightweight, weather-shedding shell in order to manage variable temperatures and keep you comfortable throughout a range of conditions. The incredibly soft, supple feel and full mechanical stretch allow for a close, athletic fit over baselayers and an uninhibited range of motion. At brew stops or in frigid conditions, pull on a lightweight shell and the Nano-Air’s thermal properties skyrocket. The left-chest pocket and two above-harness handwarmer pockets all close with trim, low-bulk zippers. The center-front zipper has a storm flap and zipper garage, a dual-adjustable drawcord hem seals in warmth and the cuffs feature a sleek, low-bulk stretch-knit inset. The jacket has a DWR (durable water repellent) finish.
  • Our updated 100% nylon ripstop shell and plain-weave lining offer generous mechanical stretch and exceptional breathability, with improved durability and abrasion resistance; both fabrics feature a DWR (durable water repellent) finish
  • Revolutionary 60-g FullRange® insulation warms and stretches; combined with the shell and lining, this creates excellent mechanical stretch and unprecedented air permeability (40CFM)
  • Articulated patterning and quilting improve shape, coverage and durability
  • Center-front zipper has zipper garage at chin for next-to-skin comfort
  • Two handwarmer pockets and a left-chest pocket are zippered, welted and low-bulk to wear comfortably with a harness or pack
  • Sleek, low-bulk, snag-resistant cuffs use stretch knit for versatile coverage and comfort; a dual-adjustable drawcord hem seals in warmth
  • Left handwarmer pocket doubles as a stuffsack
  • 352 g (12.4 oz)

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.

Men's Nano-Air® Jacket is rated 3.6 out of 5 by 12.
Rated 4 out of 5 by from Good with a Major Caveat I have worn the Nano-Air Jacket for two years skiing. I love how light it is, how it fits and how it insulates. It dries almost instantly when it gets wet. I wear it under a hardshell with merino wool underwear most ski days. If it is super cold, I add a vest. The major problem is that the face material is very delicate. The piling issues documented by other reviews have happened to me. If Patagonia added some stiffening to the fabric, it would be a perfect jacket and still very light.

Rated 2 out of 5 by from Love the concept. Problematic material Jacket looks great, fits perfectly, and is very comfortable. However, it has started pilling badly after only two months. Had to exchange it for a new one today.

Rated 5 out of 5 by from A generation better I still love my original NA, but it is wearing down after 3 yrs of extended use. Lots of piling at the collar and it is Velcro on my neck hair, and also the label Fraying off. Saw there was a new version and wanted to understand what they upgraded. Appears that the outer fabric is fundamentally better. I no longer have dog hair cling to it. Doesn’t seem to pile as much and doesn’t grab my neck. The fit is also more snug which creates a warmer wear, especially if you zip up fully I do like the new sleeve cuff, but it’s not great at holding if you pull the sleeves up. The Arcteryx Atom sleeve still has this beat. Very happy with this next generation

Rated 2 out of 5 by from As per usual... As per usual, Patagonia has great concepts involving ascetics and material design that do not translate to everyday use. I'm glad I bought mine during a sale, otherwise I'd be pretty upset. The material is very soft and comfortable, but the jacket has pilled at backpack contact points. I have only worn this jacket when walking from my car to my school. Nothing heavy duty. As someone else has mentioned, this is probably best as a mid-layer or stand alone without a pack, assuming you care about how it looks. Pilling drives me nuts, so this jacket will be relegated to limited use. Pity. Strange that this outdoor equipment-based company creates products that are so fragile, especially when you consider the pictures they use in their catalogues. They make everything look like it can be used for strenuous alpine ascents. Just use your judgement when it comes to the materials that Patagonia utilizes. If it looks soft and delicate, it probably is. Therefore, use accordingly.

Rated 4 out of 5 by from Solid, but not great fit and finish it's hard to give this a rating. i'll err on the generous side although this should probably be a 3.5 star or a wait and see (does Patagonia allow us to give follow-up reviews like Amazon?) I had the previous generation and after only a couple dozen wears was pilling badly in a number of locations. Patagonia, with their great iron-clad warranty, swapped it out for me with the latest gen. i've only worn in a couple times, but slim fit is similar to the original model (last year's) which is good since i was content with the fit of that one. the new fabric seems more durable so hopefully that means it will take longer to pill and show wear. pros: good breathability and i can wear this down to the 30s and up to mid 60s without needing to take it off. it isn't terribly wind resistant but that's the cost of high breathability. if i need wind protection, i can put a shell like my Torrentshell over it, and i'm good to go. love the soft fabric, but would be willing to give up some of that on the exterior and even add an extra 0.5oz to the jacket if that means it is more durable. time will tell if this model is an improvement over the prior one. cons (relative to old model): as far as i can tell (and remember), the zipper "garage" on this model is short/non-existent while the older model had a nice soft feel up against my chin/neck when zipped all the way up. not a deal breaker, but a surprising revelation when i zipped up all the way this morning. the jury is still out on the new cuffs. they are a bit slimmer than the old model, but they are a tighter fit around a long sleeved top in the forearms and one can't roll up one's sleeves as easily/much at all. i could imagine this might be a deal breaker for some rock climbers. what i was surprised at was the fit and finish of the how the two materials at the wrist don't line up. (see photo) i looked at the model pic on this website and it doesn't appear that things line up that well on that one easier. i may need to peak at other jackets next time i am at the store. i would have expected a higher level attention to detail given my probably several dozen other Patagonia products i've purchase over the past 3 decades. (also, the Patagonia Tag doesn't have the usual fit and finish and flush look -- i see some white at the top of the label -- hard to photograph -- i actually preferred the subtler printed Patagonia on the prior generation jacket) i have been probably as, or more satisfied with older generation if it wasn't for the horrible pilling. let's hope this new one wears better to offset the shortcomings listed above (which weren't there for the first generation).

Rated 5 out of 5 by from Perfect for cycling and touring This jacket works perfectly for the purposes I bought it for: cold weather bike commuting, and splitboarding. When riding my bike to work in temps 30F-45F, it keeps me warm and I don't get sweaty. This is a tough balance to achieve, and the nano nails it. It is also a great layer for the skin track. I find it to be plenty warm in weather down to 20F when uphill, and with a merino base and shell it's plenty warm for resort days with deep snow. Overall, the fit doesn't seem very slim in the body, so if you're thin, definitely get the slim fit size. I weigh 175lb and the large isn't tight on my body at all, and I wish it was a big snugger under my shell.

Rated 5 out of 5 by from Perfect Midlayer This jacket is the best possible midlayer you can find. Perfect for cold weather backpacking, skiing, and any other aerobic activity where you need a strong breathability to warmth ratio. Great to wear as an outer layer in Fall and Spring. Overall, top notch purchase.

Rated 3 out of 5 by from Fabric quality needs to be improved Received this as a Christmas gift and have used it for 1 week: running, some XC and downhill skiing. Overall the jacket is fine - it’s comfortable and breathable, as advertised. But the fabric at the collar is pilling significantly after minimal use. It’s like velcro on an unshaven neck, and at this rate I wonder how long it will last. I have other high-collar jackets both from Patagonia and competitor brands and none of my collars looks like this, unless I’ve used the jacket for 4 or 5 yrs. Based on this, I would hesitate to recommend this jacket to someone unless they plan to shave every time before using the Nano Air!
