For every moment of an alpine mission, the Nano-Air® delivers a breakthrough in active insulation. Put it on and leave it on through high-output, stop-and-go cold-weather adventures—its stretchy and highly breathable fabric package integrates the qualities of fleece, soft shell and puffy by combining our warm-when-wet FullRange® insulation with a plain-weave liner and a lightweight, weather-shedding shell in order to manage variable temperatures and keep you comfortable throughout a range of conditions. The incredibly soft, supple feel and full mechanical stretch allow for a close, athletic fit over baselayers and an uninhibited range of motion. At brew stops or in frigid conditions, pull on a lightweight shell and the Nano-Air’s thermal properties skyrocket. The left-chest pocket and two above-harness handwarmer pockets all close with trim, low-bulk zippers. The center-front zipper has a storm flap and zipper garage, a dual-adjustable drawcord hem seals in warmth and the cuffs feature a sleek, low-bulk stretch-knit inset. The jacket has a DWR (durable water repellent) finish.
Our updated 100% nylon ripstop shell and plain-weave lining offer generous mechanical stretch and exceptional breathability, with improved durability and abrasion resistance; both fabrics feature a DWR (durable water repellent) finish
