Because otherwise, getting out of your sleeping bag on chilly mornings sucks.

Who likes getting out of sleeping bags in the morning when it's cold out? Nobody, unless you have the Patagonia Men's Nano Puff Insulated Jacket to ease the chill. With the recycled polyester exterior and PrimaLoft One insulation, your top half will feel like you never left your sleeping bag. Wear this Nano as your top layer on chilly backpacking mornings, and layer it under your ski shell for mid-winter storms. When it gets too warm, you can pack it down into its chest pocket and clip it to your pack or harness until you need to get hot and cozy again.

  • Ultralight recycled polyester has a DWR finish to repel water, and wind glides over its slick coating so you stay warm in cold conditions
  • Insulated with PrimaLoft One for warmth (even if the insulation gets damp) and compressibility
  • Jacket stuffs into its chest pocket, and pocket has a loop to hook to your carabiner
  • Dual-adjusted drawcord hem keeps cold out and heat in
  • Two hand-warming pockets and one chest pocket store small items

Where can I find the old Nano Puff. I really dislike the new longer sizing.

Best Synthetic Jacket Around

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've worn the nano puff for about 5 years now and I just purchased me second one. The first one worn out after 4 and half years of heavy use and I couldn't have been more pleased with it. This jacket is way better than true down in my opinion because it can get wet and still maintain its warmth. If you wear this jacket in the rain, yes you will get and yes you will eventually get cold but if your running an errands and its suddenly starts raining you'll be fine and stay dry. If this were down it would get wet and ineffective in a heart beat. Its also crazy thin so you can layer your shell on top of it without issue. That's another thing about down, its bulky. This jacket is also wind resistant which is really nice and a huge advantage over fleece. Yes the price is high but with Patagonia you're buy a high quailty product that's going to last so you need to view it as an investment. The nano puff is a solid warm jacket that is functional as both a technical piece and a casual jacket. Definitely worth the big bucks!

This jacket packs a lot of warmth for it's size. Given a few layers underneath, I would trust it on any day above freezing. Serious bang for the size.

Should've purchased earlier

  • Familiarity: I've used it several times
  • Fit: Runs large

I had been eyeing this jacket for quite some time and always hesitated to buy it because of the price. I've had a similar vest from EMS (Primaloft shell) for awhile now and decided I wear it enough to justify getting a sleeved version. Essentially it is a sleeved version of the EMS vest. Love the lightness and warmth. A medium is slightly bigger than I'd want (5'9"/150lbs) but I also wear it more as an underlayer than primary jacket most of the time. I still think it's a bit high priced for what it is but seeing as I'll wear it all through cool months and summer nights it was justifiable.

nano vs. micro

  • Familiarity: I've used it several times

I tried to like the nano , but it just doesn't seem to add that much warmth compared to the micropuff, which is still quite compressable. I'm sure it has it's niche, but if I had a do over I think I would look at the NF Thermoball. For the money, the Patagonia Micropuff is an awesome piece.

Lightweight but super warm

  • Familiarity: I gave it as a gift, but have feedback to share
  • Fit: True to size

I got this jacket as a gift for my brother, but this is a very lightweight, warm puffer jacket. He didn't like the bigger bulkier puff jackets and thought this one would work, and it works awesome! We don't get that cold here in the Pacific NW, but this jacket is versatile in style, warmth, and comfort. Can't go wrong w/ Patagonia. :)

Seems to be next to nothing.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Its hard to believe something so minimal could provide so much warmth. Obviously its not enough for really really cold weather but combined with a good base layer and shell it is amazing! As a part of layering system its useful in a variety of conditions. I've worn my pull-over version 9 months of the year in Idaho. It is also remarkably wind-resistant all by itself. Only down side is the price...ouch! Look for sales.

I live in MN, would this jacket be warm enough to wear around town in 0-20 degree weather (over a sweater or a long sleeve shirt)? Thank you.

Responded on

The Nano Puff isn't designed to be the warmest jacket, but over a sweater or a decently warm shirt I think you'd be ok down into the temps listed.

Just buy one. You won't regret it.

  • Gender: Male
  • Familiarity: I've used it several times
  • Fit: True to size

I recently upgraded from a 3 in 1 jacket system to this Nano Puff and an Arc'Teryx shell. I cannot believe how warm the Nano Puff is despite feeling like I have hardly anything on. I wear it alone when running errands around town (10 degree weather) and just love how light and comfortable it is. Living in Iowa, our ski hill isn't long enough to get your blood pumping and warm up the muscles, so I wear a capilene base, then a light fleece pull over, the Nano Puff, and my hard shell. Absolutely toasty all day long despite the limited physical exertion. I am 5'9" and weigh 155 lbs. and the medium fits great.

New and unimproved.

  • Familiarity: I returned this product before using it
  • Fit: Runs small

I own a previous-season (2012/2013) Nano Puff and love that jacket to death. I wear it constantly, whether it's around town or skiing and hiking. I love it so much I decided to get a second.

Unfortunately, while much of the newer model (2013/2014) Nano Puff is the same or improved--the shell material feels better, the quilting is improved over the old model, and the zippers are nicer than the last-season model--the sizing on the new model has changed quite a bit. It's longer (which is great!) but the silhouette is significantly slimmer than the old model. To wit: I'm 6' and 185lbs. and a medium in the old jacket fits me great--enough room for a fleece underneath, but slim enough to wear a shell on top for those heavy rain/snow days. The new jacket in a medium is super tight, particularly in the chest but throughout the torso as a whole. It fails the jacket fit test (bear hug yourself and see if the jacket feels really tight or pulls in the chest, back, or arms to make sure a jacket gives you enough mobility) for me while the old one passed with flying colors. The large is still way too large.

You listening, Patagonia? Bring back the old pattern for the Nano Puff! I'll buy three!

For someone 6'1" & 155 lbs. (me) the medium size of the new version is perfect!

Any way to be alerted if the Black in Large...

Any way to be alerted if the Black in Large goes on sale? I just can't justify the price, but have tried this on and love it. No one...NO ONE puts this on sale ever?

Best Answer Responded on

Hey Butch,

Unfortunately we don't have anything set up on our sit for alerts on specific items but if you sign up for our emails we let you know what promos are going on at any given time. In all honesty though I would expect that by the time this jacket does go on sale we will be about out of the black option as it is the most popular color. Our semi annual sale should be coming up soon though so just keep checking back and cross your fingers, maybe this will be on the docket.

Found past year's model on a deal for 89$, felt like I was obligated to not pass it up. Very light, compresses and packs fairly small (about the size of a stuffed sandwich size zip-lock bag), and very warm. Took this on a late November day hike in the low 40's, threw it in the pack (32L) for when we stopped for an hour and grilled and drank beer. It was very chilly on our lookout point, but this kept me warm and most importantly, deflected the rigid wind that tortured my friends. Then, I hiked out, mostly downhill, with this on, and was very comfortable. It seemed to be decently breathable as I didn't get swampy-hot (though I wasn't exerting too intensely). Often times I'll throw it on to run an errand because it's so light and easy, anywhere from mid 40's down to 20's. The other day underneath the Nano Puff I had on a t-shirt with a fairly light flannel shirt over it, and I was cozy in the high teens. With a solid fleece underneath... I'd imagine the toastiest goodness.

cheers: comfortable. useability- being so light, warm, and packable, this will go with me on any backpacking/camping trip I go on. Daypack or weekpack, this will squeeze in (or clip on)

gripes: It is a bit boxy/roomy for me (I do have past season model), which makes me wonder if its completely thermally efficient. Also looks a bit droopy and goofy when the waist is synched tight. I am fairly short though, 5'8 170#

I would definitely recommend it, especially if you can get it for a good deal. A great piece to have in your arsenal

Great All Purpose Jacket!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This jacket is warm, packable, breathable, and lightweight. This nano puff jacket has no hood, which lends a more professional look when I wear it to work. I have the same nano puff hoodie jacket and while the hood works and fits well, it just doesnt look as nice (in work setting) as the collar on this jacket.

I have worn this outside of work during hikes, camping, work around the house and it is just the best jacket for everything.

I would recommend this jacket to anyone, and only say that if its raining out, you will likely get wet as it doesnt repel. You will be warm, but the jacket can get wet for sure. Patagonia is a rad company and this is one of the only reviews I have ever written, because I believe in their company.

I wear a 17"x34 shirt and usually buy large tagged shirts and jackets. This jacket is a large and fits me perfectly.

Bomber Puffy!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This review is on a 2012 vintage Nano Puff.

This has got to be my my most used insulation layer for my day-to-day, hiking/backpacking adventures. I use the hooded version of this jacket for as a lightweight belay jacket for the mild temperatures of Southern New Mexico. But the jacket version is by far my most used.

This thing is COMFORTABLE! It's roomy fit is a curse to some, but I find it welcoming when lounging around camp in the morning or the campfire in the evening. This would not make a ideal insulation layer for high execration outputs as it's not the most breathable, but works well for that extra kick of warmth when you slow down/stop. Packs up nicely into it's chest pocket and clips onto a harness/pack strap nicely when you get your butt back on the move. It would have to be really freaking cold to need this thing while you're moving! I'd look more into something like a Arc'teryx Atom LT if you need something to insulate while moving due to the increased breathability.

In addition to the impressive warmth of this lightweight puffy, I also find it to be just as impressive at cutting the wind. It's draw cord around the waist works well, and the lightweight nylon shell cuts the breeze quite well. It's also surprisingly durable, but far from "burly".

would this be a good breathable mid layer?...

would this be a good breathable mid layer?

Responded on

this wouldn't really be a great "breathable" mid layer. for an active mid layer, something like the Patagonia R1 or Ibex Shak would be a better option.

Responded on

I'm with Chris on this one; this is certainly more of an insulator than it is a piece you would want to be doing moderate to extreme aerobic activity in. You would sweat like a pig, I would think.

The Medium will be the best fit throughout the chest for you for sure, you could get a Large as well, it would just be slightly more loose fitting.

I'm looking at either getting this jacket or going for the pullover. Any reason to pay a little more for the jacket model?

Responded on

Great question Reyndon,
Comes down to personal preference really. Pullovers are a little more simple, and lightweight, and full zips might be a little more versatile, and easier on/off. No huge benefit to either unless you're counting grams. Interested to see how someone else might chime in...

Responded on

like ty said, for gram counting, the pullover is your option. I prefer jackets for the easier on/off. the full zipper does result in a seam where more heat loss can occur, but pretty negligible. I would say if you plan on using the jacket in setting where it's going to stay on all day, the pullover would work and save some coin. if you want to use it in variable temp settings, worth it for the jacket.
