Gone Fishingwrote a review of Patagonia Nano Puff Pullover Insulated Jacket - Men's on March 2, 2012
Most of the other positive reviews cover all the aspects of this fine jacket. It fits kind of boxy but this is a must have for warmth and comfort. I like to use it as a layer under my technical shell and it is very warm for the weight ratio. I got the Grecian Blue color on a clearance sale and have been very happy with it.
