The Nano-Air® Jacket was made to be worn for the entirety of your aerobic, start-stop alpine missions, so you’re never slowed down by changing layers. Warm, stretchy and breathable FullRange® insulation dumps excess heat when you’re working hard and keeps you warm when you’re not. Now built with significant recycled content in the shell, liner and insulation, our Nano-Air collection sets another new standard for technical insulation. Fair Trade Certified™ sewn.

It used to be somewhat mythical: A warm, stretchy breathable layer you could put on and leave on through high-output, stop-and-go activities in cold weather. That is, until our Nano-Air® Jacket broke onto the active insulation scene and redefined how we layer in the cold. Now, another breakthrough: we’ve upped the recycled content throughout the Nano-Air, from the lightweight, weather-shedding shell, to the comfortable plain-weave liner, to our warm-when-wet FullRange® insulation—all with zero sacrifice in performance. The Nano-Air still manages variable temperatures to keep you comfortable throughout a range of conditions. The woven textured yarn face fabric is soft, supple and durable, and better resists pilling than the original. Full mechanical stretch allows for a close, athletic fit over baselayers and total 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 and the Variable Conditions Cuffs have sleek, low-bulk stretch-knit insets that allow you to easily push up your sleeves. The jacket has a DWR (durable water repellent) finish to shed moisture. Fair Trade Certified™ sewn.
