Skin to the base of the route, rack up. Climb, belay, repeat until the post-climb beer, all in one jacket. Our Nano-Air™ Hoody sets a new standard for technical insulation, merging the comfort and breathability of open fleece with the protection and warmth of a puffy. Its supremely stretchy and breathable fabric package combines a plain-weave liner, warm-when-wet FullRange™ insulation and a lightweight yet durable, weather-shedding 100% nylon ripstop shell with DWR (durable water repellent) finish. The hoody has an incredibly soft, supple feel and full mechanical stretch (without moisture-holding spandex) that allow for a close, femininely sculpted fit over baselayers and an uninhibited range of motion. At chilly belays or in frigid conditions, pull on a lightweight shell and the Nano-Air's thermal properties skyrocket. 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 smaller chest pockets all close with trim, low-bulk zippers. 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.
