Approach, climb, belay, repeat until the post-climb beer‚Äîall in the Nano-Air Hoody, a warm, stretchy, breathable layer you can put on and leave on through high-output, stop-and-go activities in cold weather. Even better, we've upped the recycled material content throughout the Nano-Air, from the lightweight, weather-shedding shell, to the comfortable plain-weave liner, to our warm-when-wet FullRange insulation‚Äîall with zero sacrifice in performance. It's 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. The trim, stretchy hood is designed for next-to-noggin use, though it'll still fit snugly over low-profile helmets. Two above-harness handwarmer pockets and two chest pockets all close with trim, low-bulk zippers. The center-front zipper has a zipper garage for comfort on your chin. The Variable Conditions Cuffs have sleek, stretch-knit insets that allow you to easily push up your sleeves. When the belay goes from chilly to downright cold, pull on a lightweight shell and feel the Nano-Air's thermal properties skyrocket.
