An insulation breakthrough: The Nano-Air® Jacket featuring FullRange™ insulation is warm, stretchy and so breathable, you can wear it for the entirety of any highly aerobic start-stop mission in the mountains.
From oatmeal to single malt, the Nano-Air® Jacket represents a breakthrough in active insulation for high-output, stop-and-go alpine missions. Its stretchy and highly breathable fabric package integrates the qualities of fleece, soft shell and puffy by combining 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 so you can put it on and leave it on.
The jacket's incredibly soft, supple feel and full mechanical stretch 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 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, while stretch binding at the cuffs and a dual-adjustable drawcord hem seal in warmth.
