From oatmeal to single malt, the Nano-Air™ Jacket represents a breakthrough in active insulation for high-output, stop-and-go alpine missions. Its exclusive, 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.
Beginning with our Spring 2015 styles, we've improved our women’s fit: There’s a slight increase at the waist for shaping and to ensure the fit is truer to size. All other measurements, such as chest and hip, remain the same. Please refer to our new, updated Women's Size Chart and Fit Descriptions
for details. Note: this change applies to full-price Spring 2015 styles, not to past-season or on-sale items.
