The men's NANO-AIR Jacket by Patagonia is a warm, stretchy, breathable layer you can put on and leave on through high-output, stop-and-go activities in cold weather. FullRange insulation offers a new standard for technical insulation, merging the comfort and breathability of open fleece with the protection and warmth of a puffy while using recycled inputs to the greatest possible degree. The woven textured yarn face fabric is soft and durable, and better resists pilling than the original. Full mechanical stretch creates a close, sculpted fit over baselayers and an uninhibited range of motion. A dual-adjustable drawcord hem seals in warmth. When the belay goes from chilly to downright cold, pull on a lightweight shell and feel the Nano-Air’s thermal properties skyrocket.
