It really is warm - Patagonia Nano Puff Hoody - Women's

These jackets are so lightweight it does not seem they would provide warmth, but they really are great for backpacking and do keep you warm -with a fleece layer underneath - in the 40's and mid 30's. Packable and lighweight. I can't use down so I was looking for a down alternative. This jacket worked very well backpacking.
