This jacket has a very nice fit and it's not all puffy like some vests, yet for the price, there is no real warmth at all. It does nothing to keep the core warm at all but if you're looking for great style, this is your vest.
Hi Susan, we're sorry to hear that the Nano-Air Vest isn't keeping you warm enough. Try taking a look at our Women's [Better Sweater Fleece Vest](https://www.patagonia.com/returns.html). The Better Sweater is awesomely warm and still has the simple style as the Nano-Air.
I have a lot of Pati clothing. These is a standout. Wow, so warm! So light! The collar doesn't but my chin like so many vests do. The pockets are deep and I love that there's zippers. Easy to layer and again, so perfectly warm. I LOVE this for winter running. I am buying the jacket next.
Unlike my other Patagonia vests in S that fit perfectly snug with room for light sweaters, this one seemed very tight along the hip line -- and I have no hips. The top poofed out a bit probably because of the tight bottom. For reference, I'm 5'11, 135 and typically wear small in most outerwear. Bummed that I had to return.
Hi Karen, thank you for passing along this feedback about the fit of this vest. We're sorry it wasn't right for you! You might be happier with the fit of the [Down Sweater Vest](https://www.patagonia.com/product/womens-down-sweater-vest/84629.html?dwvar_84629_color=BLK). If you like, we will be happy to help you with specific measurements so you can be confident about a good fit. You can reach us at (800) 638-6464, or via live chat on our website.
Strange fit at hips and shoulders
Patagonia vests usually fit me well, but this was too tight across hips and too big in the shoulder area, so it would not lay flat on shoulders. Therefore I had to return it and bought the nano puff vest.
We appreciate your feedback and we're sorry the fit wasn't quite right. The Nano-Air is a slim fit design so it may feel tighter than our "regular" and "relaxed" fit vests, but the fabric also has some stretch. Our product design team will take your input into account with any future changes. Thanks for the review, Joanne!
Ive been waiting for a vest like
I have been looking for a replacement for a vest that has seen it all- from summits to sea, long shifts on a medical floor; it was my everything beyond providing warmth, range of motion, breathable, thermal regulation, and pockets for supplies.

Light, Versatile and Warm
Love it so much this is my second nano air vest. It is perfect for trad climbing and back country skiing - small and packable with enough core warmth, and no bulky arms. All pockets are zippered which is a must have for me. The fabric is matt and decently resistant to stains. Perfect!
Well designed piece ready for anything
The Nano-Air vest is light yet warms just enough when one layer is too little. It also rolls up into nothing to pack for later when the evening cools down. Pockets (3 of them!) are generous with hidden zips. Past items I ordered were mix of XS and S. As the Nano-Air is a slim/fitted cut, I ordered S which is cosy and sits comfortably over shirts wh...

We appreciate the valuable details on fit, sizing and how you've used your vest, Lorna! Our Nano-Air Vest has a "slim" fit design so we can understand why some prefer to size up, while the Nano Puff styles are a "regular" fit and most people will choose their usual size. Thanks for sending in your helpful review!
Better than the newer version
I love this vest. I lost the one I had in green, so I finally had to buy a replacement. Unfortunately only black was available. The black is just as great as the original green, but I do wish you had more colors in stock. This vest is the best piece of clothing ever. It's actually worth the price.
Keeps me warm
I bought this vest as I needed something that would keep me warm throughout my daily hike without keeping me too warm. Im usually overheated about half-way through with normal jackets, so I wanted some warm, but lightweight which would let my arms breathe! This vest accomplishes all of those things. I live in the high desert in Central Oregon, so m... Read Moreornings can be in the high 20s, low 30s, even in April. The only thing I would note is that the vest runs small. Normally, I wear a medium with my Patagonia jackets, but believe the slim fit description...I had to switch out for a Large. I love the fit, now, and I know this will last me for years!
Comfortable and Warm
I tried 3 sizes. XS-I couldnt close to zip. S-It was form fitting. M-It was only slightly bigger than the S. I decided on the small because I wasnt going to wear a heavy shirt under it. So far Ive worn it for walking and playing golf. The pockets are just the right size for gloves, golf balls, or phone.
Light and Comfortable
I love Patagonia clothing, but sizing is tricky sometimes. My usual size small was too tight. I exchanged it for a medium and now fits perfectly! Overall the fabric is light and confortable. I got the Catalan color and I love it. For reference Im 57, athletic build, and 140 lbs.
Nanor air (B)est
The vest is incredibly warm and comfortable and packs into nothing. The uses for it are so versatile - work, hiking, skiing, running, watching a film. etc. I think I will be taking this with me wherever I go - It's also kinda long which is good, but if your hips are on the wider side, it might be a bit tight at the bottom. A zipper on the si... Read Moredes might be good to be able to adjust this to more body shapes. Nonetheless, super happy with the best of vests.
Great Running Vest
As I've increased my milage in winter, I've realized that I don't like a lot of bulk on my arms and core; I get overheated really easily but often a base layer isn't quite enough. This vest is a real problem solver. It's as soft as butter, light as a feather, and water beads up and rolls right off. Great pockets. I LOVE IT!... Read More
Is it just me, or have sizes changed a bit?
I love this vest. I love the color. I love the material it is made out of. That said, I had to exchange from original M size for a L but now it fits fine. I'm older now and sizes and my own body have changed a bit. I'm not fat but neither is my body like it was when I was 35 or 40. Maybe there's a nice way of getting the size scene a...

Versatile Fitted Vest Over Baselayers
I own the Nano Air Hoody Jacket and love how incredibly soft, warm, yet breathable it is. It is the piece I grab almost daily for both work and hiking all spring/summer/fall-long. I have had the Down Sweater Vest and Better Sweater Vest for many years and always feel like they are warm but not warm enough - prob b/c they are both slightly too roomy... Read More on me. I have those in XS and bought the Nano Air Vest in XXS. I am 5'1, 95 lbs and usually a size 0-2. Waist is 25. I am normally XS in everything Patagonia except their base layers I am XXS. So I decided to go with XXS for the Nano Air Vest and glad I did! It is definitely form-fitting and close to skin. It fits well over my base layers and both the Patagonia Capilene Thermal Crew and Capilene Air Crew/Hoody. Despite being air-light and not at all puffy, I find it warmer than the Down Sweater Vest and Better Sweater Vest. It is perfectly streamlined and, unlike my other two vests, it does not feel bulky at all under a winter jacket or even under a roomier fleece such as the (Women's size XS) Re-Tool Snap-T Fleece or (Men's size S) R3 Fleece Hoody. Really glad I invested in this versatile vest to keep me my core warm over base layers! Will be awesome for nordic skiing and summer running/hiking! I know this will be my go-to all year long and especially in cold weather!
Versatile and Essential Piece
Bought this on the recommendation of a friend, and I'm so glad I did. I had read that it runs large, so ordered both the small and extra-small. I'm 125lbs and 5'5". The extra-small was too tight around the hips on me. There is enough room for me to wear this over something bulkier than a simple underlay, like a flannel shirt. So... Read More far, I've used it for biking, hiking, skate-skiing, and snowshoeing and have found it to be a versatile piece - am so psyched I shelled out the money! Even better, I found myself wearing it around the house yesterday -- it's a soft, quiet fabric (no rustling! you know what I'm talking about!) so I don't feel like I'm wearing outdoor gear inside. I got it in black -- it will go with everything.
Nice to Have a Fitted Insulated Vest
I got this sleeker insulated vest after "losing" one of my puffier vests to a daughter who seems to have forgotten it was mine. I liked the bright blue color, as it works with the accents in my plaid shirts. I'm not entirely sure it's as warm as my quilted insulated vests, but that could be perception based on the sleeker design... Read More. The fit does allow for the vest to look less outdoorsy casual, although it's still not dressy; may or may not work for some places' concepts of business casual.
Room for Layers
I bought this in my regular Pat size M because many reviews said runs large. I am mostly M and sometimes S in Pat. Having also tried the Nano Puff which was tight in hip, it does run large comparatively, but this vest doesnt have any extra room on top, it just gives a bit of room for a womens normal size hips! For me Pat coats/vests are sized too s... Read Moretraight up n down - like mens clothing. Ive tried L when M doesnt fits which are always WAY too big. Happy I found one that gives room for winter clothing underneath, is comfy, soft, flattering, well made, n lots of pocket room.
Excellent lightweight yet warm layer
I love this vest! I actually find the Nano Air vest a little more useful than the Nano Air jacket, something about this super lightweight, flexible yet warm layer works great for me in vest form. It adds just that little extra warmth so I love it as a vest. It's awesome for cold weather hiking or running, and I also use it as a mid-layer, over... Read More a baselayer and under a fleece for example, giving me that little extra warmth for cooler or windier days. It's slim enough that it works to wear that way without looking too bulky. I also wear it casually, it looks great! For me this fits true to Patagonia size - I almost always wear a L in Patagonia jackets/tops and took a L in this as well. It is slim fit and nicely shaped (better fitting than the down sweater vest or nano puff vest for example, at least on me). Thank you Patagonia, this is an item I will wear for years.
I bought 2 of these vests to wear casual, work, hiking, scrambling so indoor/outdoor. Im normally a solid M/S 8-10 top and bottom in Patagonia. Jackets/vests are a mystery. Have a couple M jackets, but some returned due to tight in hips. The size chart for this Nano Air (slim fit) vest is exactly the same as for the Nano Puff (regular fit), however... Read More the Nano Air seems like regular fit (evenly top and hip) - it fits larger than the Nano Puff which is reg on top, but slim in hip. Just a bit misleading when trying to decide on size. Almost bought both M and L which I hate doing... in the end if you are usually M or 8/10 this vest is good with or without layer, but its definitely not fitted for me. Cobalt beautiful and Coral very bright Keeping both - soft and very well made with great pockets. More colors would be great
Nice and lightweight but pills
Has not worn well at all. I'm not sure if the fabric in this product has been changed, but the vest I have has pilled horribly around the pockets. Lint or whatever I'm around sticks to it where it has fuzzed out. Very disappointing! Otherwise, warm and lightweight like I needed.
Hello Jennifer, we are very sorry to learn about the pilling issue you experienced with the vest. We recommend using a Sweater Stone to remove the pilling but there are also other similar products and techniques that will also do the trick. You are also more than welcome to [return](https://www.patagonia.com/returns.html) it to us under our Ironclad Guarantee.

I needed a vest that was lightweight but warm, non-down, and a good layer for backpacking, mountain biking, hiking, and all winter sports. This vest is it.

Good cold weather running vest.
I got this vest to run in. I originally ordered a small, but the top and arm-holes were way too big, although the bottom fit very comfortably.
