Patagonia Women's Nano-Air Vest

An insulation breakthrough: the Patagonia Women's 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.

Icy runnels up high, sun-warmed rock down low: springtime means sendin’ temps. Whatever your preferred medium, core warmth matters and Patagonia's new Nano-Air Vest keeps pace throughout high-output, stop-and-go missions in variable conditions. 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 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.

Stretchy

The Nano-Air™ uses FullRange™ insulation with 4-way mechanical stretch, so it requires minimal stitching for stabilization. Pair that with a stretchy liner and shell, and the Nano-Air™ delivers unrestricted movement for highly dynamic activities. 

Breathable

The incredible breathability of our FullRange™ insulation (40 CFM) means you can go hard all day with zero swamp factor and spend less time messing with layers.
The 100% nylon ripstop shell still protects from light precip and all but blasting winds.

Nano-Air Insulation

The ultimate insulation link-up of stretch plus breathability, Patagonia's Nano-Air collection places their 60-g FullRange Insulation between a light but durable shell and liner fabrics to create a product exclusive to Patagonia and unlike anything else out there. Offering excellent temperature regulation and unrestricted movement, it's ideal for continuous wear during highly aerobic mountain missions.
