Rated 4 out of 5 by from Perfect except... I bought this because I love my black nano puff jacket. It's so light weight but warm and versatile (can be relatively dressed up or dressed down). The size and fit of the vest are the exact same as the jacket and I love everything about it EXCEPT the color. I love the French red but the zippers are aqua/teal. In the photo they look more grey. I'm torn about whether to keep or return it because I think this will limit the color/style of tops I can wear under it. The aqua/teal accents just make it look so much more casual

Rated 5 out of 5 by from wear it everywhere i got this as a gift, it wasnt what i wanted but we were out of town and it was cold so i wore it, and loved it. it fits under my 2 piece northface coat. it has a nice inside pocket for keys or a creditcard, i wear this and dont take a coat or purse when running around town. i hiked through some pretty heavy underbrush and then stood way too close to a fire, but i didnt notice any snags or scorch marks.

Rated 5 out of 5 by from Light but mighty! I owned a Nano Puff jacket for many years and love it for its versatility. The jacket was really warm and also light at the same time. I decided to finally purchase the vest for a great under/over layer for the changing seasons. The vest has a pretty feminine fit. I'm 5'8", 135lbs. with a slender build and I purchased a medium. Its a perfect fit, not too tight while not appearing baggy. Its a great, long-lasting piece to have for the outdoors as well as a night on the town.

Rated 5 out of 5 by from Perfect vest weight, insulation & style I have been looking for many years for the 'perfect' black vest, and I finally found it! I love this vest, and I am so happy I waited to buy the right item. It is the lightest-weight vest (which I love!), and the insulation is fantastic! At the same time, I also purchased two different colored nano puff jackets, with the same thinness & insulation, so I am good to go through at least 3 seasons and a lot of dog walking! I live in the mid-west, so who knows, this may even take me into the coldest winter days underneath my winter parka!

Rated 5 out of 5 by from Everyone needs one of these I've had my white one for a couple of years. I specifically bought it for use in the office all year round. It keeps me warm in the summer when is the a/c is blasting and of course, in the winter because there's just never enough heat in my north-facing office. I also own a nano puff jacket, which pretty much goes everywhere I travel and is enough for the milder winter days in DC. I really like the freedom of movement that the vest offers, i.e. sleeves feel so bulky sometimes. I've used this more and more in our business casual attire workplace, instead of sweaters and blazers. I'm about to purchase a second one for my real life -- a darker color this time because it is going to get a lot more use while doing fun stuff outside! I find this to be a better liner to the Barbour classic Beadnell jacket instead of the fleece one that is made to go with the jacket, which is so much bulkier.

Rated 4 out of 5 by from love my new vest I love my new vest. I have received complements on it already and its only been a few days. The only fitting issue that I have with it is the weird way it gathers on either shoulder.

Rated 5 out of 5 by from Light, comfy, and warm Great for layering over long sleeves or regular shirts - I wear mine all the time going to and from the gym on chilly mornings. Love the bright color and as always Patagonia quality.

Is this fitted or is it more of a boxy fit. My size choice will depend on the type of fit.

​Patagonia considers this vest to have a regular fit. Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers.
