We just ordered husband and wife nano puff vests. We have loved our jackets and we are excited about the summer option to have these vest! They are the best for travel!

My wife got this vest to wear under her shell jacket. It's lightweight/low profile insulation is perfect. Not bulky but still warm. The vest is long so it provides great coverage. We recently took a ski trip and she didn't take it off, that's a good sign I think.

I am not typically a huge vest person. Mainly because I am pretty short so most puffy vests tend to engulf my neck area and I just can't seem to get the layering right. However this vest is KILLER! It is super thin and lightweight which I love and I can layer it with anything, it even fits under an already bulky jacket. I've warn it almost every day, and not turning back!

This vest is super versatile, looks great, and keeps me warm.

I picked up this vest for my mom due to her not so subtle hints about wanting a down jacket, and she is more than happy with it! The lightweight construction paired with great warmth makes this vest a fantastic midlayer when pursuing winter activities or an even better outerlayer when walking around on a chilly fall day.

I gave this as a gift to my mother and she had this to say: "Yes, I love this vest. So comfortable, warm and light weight. I got the feather grey color and its very stylish. The arm holes have elastic material around them and it holds it sleek against your arm, it does not stick out. Overall a very stylish vest. "

I bought this for my roommate for Christmas. and she has now stated that she is forever a never nude, because of this vest. She put it on and didn't take it off. I have the full jacket version and it's honestly my favorite layer that I have. It's the perfect amount of warmth under any shell, or even by itself. The vest is a great option for spring/fall hiking where it's chilly but warm enough that you want your arms free to breath. I would recommend nano puffs in general to EVERYONE, but the vest is a great option if you need extra warmth around your core.

My client Lisa bought this for a camping and backpacking trip in Grand Teton National Park to keep her warm during cool August/September nights. She instantly fell in love with the vest and noted it as being a fabulous piece to add to her camping set-up! It is so packable, she didn’t notice the extra weight on her 4 day backpacking trip, and she told me should could literally stuff it anywhere. It kept her core surprisingly warm for how lightweight it is. At her height and weight, the small fit perfectly with just enough room to to throw a few layers on under, or over it. Let me know if you have any questions regarding this vest, or if you need help making sure that it is the perfect piece for your build.

This was a Christmas gift for my mother-in-law––she ended up liking it so much that she picked up another color. She's around around 5'4" and 110lbs, and the XS was a better fit than the S. It provides considerable warmth in a surprisingly lightweight package.

Vests never used to be one of the first things I thought of when it came to layering up for warmth, but this one definitely changed all that. I am cold almost all the time but this vest helps keep my core warm when I get a bit chilly, no matter where I am, whether it's sitting all day in the office or braving the elements for a hike. The best part is that it packs down super small (into itself) so I really do end up wearing/taking it everywhere with me... Just in case.

I have it in white and I have to say that with time the trim around the armholes has become less white than the rest of the vest. It's not really a huge deal and I'm not sure anyone else would even notice it. Also, as some other reviews mentioned, the armholes are weirdly tight. I didn't really notice it until I was reaching and moving my arms a lot and found them to be the slightest bit restrictive.

A little more length in the back would be nice but I prefer everything long. Overall, I love it and would recommend to anyone seeking a versatile and packable insulated vest.

Vest runs true to size. Very warm and great for layering. Packs down to nothing so is great for traveling.

Patagonia has done it again! This layer is so light and versatile; I wear it skiing, I wear it to work, and I wear it everywhere in between. I know I'll have this layer forever and could not recommend it enough!

I have this vest in red it is very versitile. I wear this with a fleece under it under my ski jacket over it and it is the perfect thing to keep my core warm, but leave flexibility in my shoulders and arms inside the jacket. It is also super cute for daily wear! If you want a tight fit size down!!! I wish I would have got an extra small (however I have a small bust).

Awesome and warm Patagonia vest -- this is 2nd vest i have owned from Patagonia and i like the nano puff because of its functional and technical aspect. I can wear this to the office but also wear it skiing and hiking and it is a great midlayer. I would only say i wish it was a bit longer on my torso. For reference I am 5'5" and 135 lbs and got a size small which fits well!

This vest has lasted me 5 years - And I haven't worn it casually: I wear it everyday during the fall and winter as part of my normal ensemble , I wear it hiking, fishing, running, camping, skiing. Over sweatshirts, under zip-ups, I really like the vest. It shows very light wear at the seams and a few tiny holes from fish hooks. The only reason I am replacing it after 5 years is that it seems to have lost a little warmthy loft...However, it could also just be me wanting to have two of them. Have I tried other vests you ask? I have, and I returned them.

And even better for the winter chill! This vest is such high quality and slim enough to layer under without getting all bulky. It's cute and slim and It can squish into any day bag! Highly recommend. The Small was a bit tight, might go for a medium next time.

When it comes to down I love Patagonia because of their sustainable practices and comfort. I've never had a bad experience with them before and the Nano Puff Vest is no exception. It fits perfectly, is outstandingly warm, and looks decently flattering (as much as a puffy can). I ordered a small, and it fits true to size. It packs down small and can fit inside tight spaces so it's easy to carry around for when you might need to layer later.

This vest is extremely versatile and warm considering how small it packs down. I wear it touring regularly because it breathes well and provides a great layer of warmth to keep in your pack.

This was given to my sister as a gift, and she likes the simple style and fit. It's very light, and a nice top layer for most outfits and occasions. Great buy

Great vest for layering on those colder days or wearing as a top layer when it warms up. Packs down fairly small if you need to stuff it in a pack. Bought this as a gift and she loves it.
