Patagonia Men's Nano Air Vest

Icy runnels up high, sun-warmed rock down low: Springtime means sendin’ temps. Whatever your preferred medium, core warmth matters and our Nano-Air® Vest keeps pace throughout high-output, stop-and-go missions in variable conditions. 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 nylon ripstop shell with a DWR (durable water repellent) finish so you can put it on and leave it on. The vest’s soft, supple feel and full mechanical stretch allow 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.
