Patagonia Women's Nano Air Vest
An insulation breakthrough: the new Nano-Air™ Vest 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.
The Nano Air 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 vest’s incredibly soft, supple feel and full mechanical stretch allows for a close, athletic fit over baselayers and an uninhibited range of motion. The left-chest pocket and two 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 armholes and a dual-adjustable drawcord hem seal in warmth.
