Great jacket that I bought for my son. Slim fit, but true to size. Looks good and keeps him warm.

Got it for my husband... i have had mine for 6 years. The nano puff is perfect for California weather. Light enough to layer or wear with T-shirt.

This is my second Nano Puff Jacket. I travel frequently and this is perfect jacket to stuff in my backpack. Rain and wind - perfect. Down to 25F, perfect. Below 25F, a sweater and the jacket - perfect.

Exactly what I needed lightweight and warm great for layering

Great jacket. Super warm and comfortable. I am usually between a medium and a large. Went for a medium and it’s a bit on the snugger side which is okay for a base layer. Sleeves are long which is often the case with Patagonia. Overall a great jacket. If you are between sizes I might size up for the extra room if you plan to layer under it.

So happy with this jacket, very warm, very comfortable and the fit is perfect!

Love the jacket! I would definitely recommend it particularly because of the insulation properties even when wet.

This is a really well made jacket. I'm 6 foot 210 pounds (man) and am normally between a Large and XL. I have other Patagonia jackets in Large so figured I'd try Large but was worried after reading reviews of it being small. I'm happy I went with Large as I would not consider this a slim fit. It's a normal fit but just not the huge room you'd get in a bigger puffer jacket (it's a light puffer). Plus the sleeves are long so I feel like Large was the right call. I can still get a thin vest or fleece under it. Top notch jacket for 40-60F (lower if layering). I travel a lot and it compacts well.

I bought this for my son for his birthday. My son Loves it! So warm without the bulk, can be dressed up or down. Great quality

I managed to get this jacket on sale, but I think I’d pay full price for it! For a warm jacket, it’s pretty form fitting and true to size. The fact that it’s lightweight and can be collapsed into a tiny pocket is a plus!
