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
  • Item #PAT3379

What do you think about this product?

My everyday wear jacket

Love the lightness, packability and ridiculous warm out of something so small. This jacket was the first time I had to use Patagonia's repair policy to because of a crazy all teeth dog named Charlie. Happy to say that the repairs came back beautiful and I have my favorite jacket back in one piece.

My everyday wear jacket

Anyone else have trouble with the stitching coming undone on the Nano Puff? I love the jacket but insure of the quality.

Is this jacket reversible? It looks like that in some of the photos.

While you can wear this jacket however you want to, it is not meant to be a reversible jacket. We include the inside view of the jackets to show construction of the piece. Some brands can have a jacket that looks great on the outside, but is actually constructed very poorly. Showing the inside lets you get a better look at the seams. Patagonia is well known for having some of the most well made items on the market, and if you are interested, I would definitely encourage you to check this one out.

Is this synthetic good for inactivity warmth, like down is?
Basically my purpose is to have a packable jacket that I can throw on when I stop activities.

Hey Tim! the synthetic performs great as an insulator and its benefit over down is that it can help keep you warm even if it gets a little damp. This would be a great option to keep around if you need lightweight, but warm layer for staying warm in between different activities.

My cycling layering is UnderArmor, if somewhere below freezing to zero I add Columbia Omniheat , and then vented cycling windbreaker jacket. If I ever flat tire, or breakdown I'll be in trouble. The packable jacket is something of a emergency bail out. Same concept of hauling sleeping bag around in your vehicle all winter.

I suppose the next question is Which packs smaller down or synthetic. Or is that splitting hairs?

thank you.

How does this piece compare to the Marmot Quasar? I think the Marmot is down and this is synthetic so this may hold heat better when wet. But what other practical differences should I expect? Thanks.

What temperature range do you think this jacket works best in? Also, can this jacket zip into an outer shell?

Best Answer


I am going on my second year using this jacket. The temperature rating is up to you as that really depends on what you are doing and your other layering. I have used this as everything from a casual jacket in 40-50 degree weather to a layering piece in sub-zero temps, while alpine climbing and backcountry skiing. This does not zip into an outer shell, but is very trim so you would have no problem fitting that under a shell. I have been nothing but please with this jacket so far. If you have any other questions or want to get an order set up, I would be more than happy to help!

I am 6 foot and 160 pounds. I am debating whether or not I should get the medium or large. I don't want to be swimming in it, but I want to make sure it's long enough for my waist. What size would be best for me.

In the picture the black and gray jackets look to be more form fitting vs the pictures of the other colors. Is this the case?

When will you have Malachite Green in Large back in stock? I've been waiting to order one!

I live in MN, would this jacket be warm...

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.

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

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.
