Soft and snug
I swear this for my daily walk. I live in hilly country. The jacket fits snugger on my hips than I would have suspected so Im glad I selected a large. Im 510 and 141 pounds. My hips, at widest, is 40 inches. The large is roomy at the shoulder and a nice sleeve length but when zipped I wouldnt want it any smaller for the hips. Im undecided how I fee... Read Morel about this in windy conditions for warmth. I havent had the jacket that long. Overall Im happy with the purchase. There is already a snag on the front of the jacket however. Ive only worn it a few times so thats disappointing given the price I paid
I love this jacket. It is so hard for me to find a jacket that fits my petite body and the XXS fits me perfectly. It's simple and elegant, perfect for everyday use, work, travel, hiking. It's very light, but keeps you warm in mild spring/autumn weather. I've had it for over a year and washed it several times (gentle cycle, hang to dr... Read Morey) and it still looks like new. One of my best Patagonia purchases!
Warm and lightweight
I bought this as a warm, active layer for hiking the Grand Canyon. I think it will be perfect and also see me wearing this under my Patagonia rain jacket on cold and rainy days. The only thing keeping this from a 5-star for me is that for me it was longer in the torso than Id like.
I love my Nano-Hybrid (I've had it >than 5 years) and was disappointed Patagonia wasn't making them anymore. I tried the Nano air hoping it would provide me with the same performance of the Nano hybrid. I ordered a size L and it was ill fitting all around, too large in the abdomen area, tight in the bust (I don't have huge boobs e... Read Moreither). I didn't bother exchanging for a size M because the bust was already too tight in the large, but it would have probably fit my waist line a bit better. For reference I own the Nano Hybrid in a size Medium but sized up so I could wear some thicker layers underneath and have a looser fit. In the meantime I'll keep rocking the hybrid until I develop wholes around where my pack straps sit (starting to get worn thin), otherwise the jacket has held up well. It's my favorite cold weather layer for high aerobic activities.
Surprisingly warm, fits great
Love the nano air product line. This jacket is super light weight and warm at the same time. The small fits perfectly, with enough room for hips and bust, without being baggy. Normally I am between a small and extra small. The navy color is classy too. Highly recommend!
Love this jacket
This jacket is super versatile. Can be worn alone on less cold days or when active or under a jacket when it's colder or for dog walks. I almost bought a size up based on reviews but am glad I didn't. It fits like a glove over a long sleeve tee or baselayer and I barely feel like I'm wearing two jackets when I layer it under my Nano.... Read More Super comfortable, keeps you warm.

Great jacket, but slim fit doesn't work for me
I ordered this jacket without realizing it was slim fit, because my husband has the men's small and I regularly borrow his so buying my own seemed like a no-brainer. I initially ordered my usual women's medium and was shocked that I couldn't even get it zipped across my chest until I looked more closely and saw the "slim fit&quo... Read Moret; indicator. I exchanged it for a large, which fit across the chest but was too long in the torso and arms, and the extra fabric in the shoulders was clearly visible. I ended up returning it. I love the fabric, weight, and warmth of this jacket and am so sad that it just isn't made for those of us with short, curvy torsos. I wish there were a Nano Air option that was.
Warm So Far
Have tested this jacket while running in 30-40 degree temps, definitely warm with only a short-sleeve t-shirt underneath. Still need to try it with truly cold temps. I typically wear a small but bought a medium based on other reviews and it's a bit roomy for me; it works, but maybe the small would have been better. Sleeves are long on me but t...

Great working base layer!
I love my new jacket! It is a super low profile & packable light puffy and great for my last backpacking trip but still unpacked for a warm layer when temps got down.

I am a huge fan of the Nano Air so far. It fits snugly but comfortably, good motivation to stay active!

Smaller fit than other Patagonia jackets
I wish this worked for me! The fabric is really nice, and I like the slimmer profile and seamless look, however, the fit is different from other Patagonia jackets. I'm consistently a small in Patagonia jackets, but with the Nano Air, the small was tight across the bust and under the arms. The medium was too big: it was baggy in the chest and t...

Amazing layer to use for aerobic activity on really cold days!
This is my favorite piece for really cold days! It is not bulky and it is SUPER warm and breathable! My only issues are the collar is too high and the length is too long - these are ongoing issues I have with most Patagonia jackets. I am an xxs and I am not sure if Patagonia does user testing with true xxs women (i.e., those under 5'2). If you... Read More ever need a wear tester, let me know! I am 5'0 and active :)
Too long causing bunching at the waist. But v lightweight and warm.
It was as claimed: lightweight and warm, although I only tried it on inside. It also was soft inside. I sadly ended up returning the product because it was too long. After I zipped it, it had a huge bunch at the waist. I tried it in a Small as well but the arms were too big making it look awkward. It may work for a different body type.
Excellent warmth and breathability
These jackets are one of my favorites. I love the soft cozy feel of the Nano Air jackets to wear around the house or around town but I purchase these for athletics. I regularly wear them hiking, biking, and running. I own several to make sure I have at least one to wear when the others are in the wash. In Southern California it does not get extreme...

Light weight warmth
Nano's are amazing for how light weight they are but still warm. I live in NC and a nano is about all I need in the winter. I bought the nano air to replace my nano puff which I unfortunately ripped on some metal fencing. I like the jacket is not quilted. The arms are way too long for me.

My most versatile jacket for cardio
I bought this when it first came out several years ago and I wear it ALL THE TIME for trail running or hiking. It is so light, it wicks well, and it's durable (I've taken some nasty spills in it on the trails).

Very nice but not for me
I purchased this jacket after seeing one of my friends wearing it. I was looking for something warm but lightweight that I could wear while taking walks and hiking outside in the winter in Boston. I didnt end up keeping the jacket because the profile was very narrow. I am normally a medium and had to go up to an XL for a comfortable fit, making the... Read More rest of the jacket quite oversized looking but still awkwardly slim. I wouldnt recommend this jacket for anyone with an hourglass or curvy shape but otherwise it felt amazing.

Not the best looking, but great for layering
I'm not in general a big fan of Patagonia, but I like this jacket a lot. I'm not thrilled about the look, but warmth vs weight is important to me. This jacket has been perfect for me in many situations as a second layer when the total number of layers is 3. Got one for my spouse too
Super versatile jacket
This is one jacket that does it all. I was tired of constantly shedding my puffy layer , then putting it back on when on the move and was looking for a solution. The nanoair was toasty enough on very cold 20F mornings with just a t-shirt underneath when I started out on my hikes. Then as the day warmed up into the 60s, I was still comfortable with ... Read Moreit unzipped. I could not be happier. This will be an amazing layer to take backpacking as it will replace at least two layers and it appears to pack down quite small. I am actually very surprised how warm the synthetic insulation is. I really had my doubts about this piece but those were put to rest. This jacket is now an essential piece of gear I plan to take traveling, backpacking and mountaineering. Size small fit great with enough room for long sleeve layer underneath (I am 53 and 115lb). Love it!!!!!
A must have jacket!
This jacket is amazing and I highly recommend it! This is my second nano air (my first is still much loved and use) and compared to the older version, this one has a very slim fit. You can fit a few thin layers under this jacket, but I wouldnt recommend bulky layers under this puppy.
Too big. Terrible fit. Again.
I have written several reviews regarding the sizing issue patagonia has and they dont even reply to my comments anymore. No wonder, the complaint is always the same. And once again, this is way too big. I cannot understand how is it possible that M is this large, since I am 5.9 and weigh 135. This fits me like a Large or maybe even an XL. Seems lik... Read Moree even a small could be too big. Its too roomy, almost has a sack-like fit. It just doesnt look good and makes me sad, since it is beautifully made, so light and a lovely colour. Also, the sleeves are a nice length. Unfortunately I have to order online, since I dont have a physical store nearby ... And every time I order Im not even excited, because I know Im gonna have to send at least half of the stuff back. How can the sizes be so inconsistent? Such a shame.
Hi Maja, we're very sorry that sizing has been an issue for you. Your reviews help our designers know what's working and what's not. We truly appreciate you sharing your thoughts and we'll pass them along to the appropriate members of the Patagonia design crew.
Best. Jacket. Ever.
I bought one for myself and one for my husband a year ago. Its now the only jacket we wear. Light as a feather. Wonderfully soft and comfortable. I smile every time I put it on. We live in the Andes of Ecuador where the weather changes constantly throughout the day. When the sun is out, its hot; when it dips behind a cloud, its cold. It often rains...

Exactly what I was looking for.
I needed a mid layer that wasn't boxy but still allowed for movement in my (rather broad) shoulders and was long enough in the arms and torso. The fact that this jacket ticked off all those requirements PLUS is water resistant, super soft, lightweight, and was available in an amazing color (Catalan coral) makes it worth the cost in my book.
In 2015 I bought my 1st Nano Air jacket. I wore it everyday walking 500 miles across Spain, and just about everyday for the next 2 years. I love this jacket!

Thanks for taking the time to leave feedback about our fabrics, and for sharing the story of your adventure through Spain. Some fabrics are more prone to pilling in high friction areas. This can be resolved by using a de-piller or razor. But as always, your satisfaction is guaranteed so you can [return](https://www.patagonia.com/returns.html) it for warranty.
Great in between jacket
I give this jacket a 4 instead of a 5 just because I often find myself wearing my R1 techface hoody more than my nanoair (yes, I am a huge fan of patagonia and it is all I wear).

Patagonia Women's Nano-Air® Jacket
I have an older version of this jacket and it is my all-time, go-to fave. I bought the xs (same as my old jacket) and the jacket is too tight around the chest area and the sleeves are too long.

Thank you for the feedback on sizing and the color options.

As far as colors, we will typically offer colors similar to what you've mentioned in the fall seasons!
Too tight in the shoulders
These are great jackets, but for some reason Patagonia has made them very tight through the shoulders. I am 5'8", 138 pounds, and I had trouble getting my arms in the sleeves of the size large. I even tried on an XL at a local store in a different color and had the same problem.
Best Lightweight Ever
I wanted a jacket that was breathable as I hate feeling stuffy heat. I have not done anything aerobic in it yet but wearing on plane and traveling from rainy WA to hot CA - in the cold/hot/breeze/still it has kept me comfortable. The fit is flattering and the jacket is comfortable on the skin so I can wear a tank or short sleeve tee under it.
