The Patagonia Men's Nano-Air Hoody sets a new standard for technical insulation, merging the comfort and breathability of open fleece with the protection and warmth of puff brick quilting. Its breathable fabric package combines a plain-weave liner, warm-when-wet FullRange insulation, and a lightweight-yet-durable, weather-shedding shell with DWR (durable water repellent) finish. The Hoody has an incredibly soft, supple feel and full mechanical stretch that allows for a close, athletic fit over base layers and an uninhibited range of motion. The trim, stretchy hood is designed for next-to-noggin use, though it'll still fit snugly over low-profile helmets. The center-front zipper has a storm flap and zipper garage, while stretch binding at the cuffs and a dual-adjustable drawcord hem seal in warmth. the inside of each sleeve does have a tiny stain. I found a mark on the back of the left arm sleeve as well. may or may not come out with proper stain treatment and wash. all sales final. A3
