Measurements refer to body size, not garment dimensions, and are in inches, unless otherwise noted.
Men's Fit Guide
Though each Patagonia® product is designed and shaped specifically for its intended use, we can generalize our fit descriptions in four ways:
Formfitting: Conforms to the body’s contours.
Slim Fit: Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.
Regular Fit: Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers.
Relaxed Fit: Drapes loosely on the body.
The Nano-Air® revolution accelerates. The Nano-Air Light Hybrid Vest delivers for high-exertion athletes and cool-weather missions by combining 40-g FullRange® insulation, a flyweight shell fabric and an airy, wicking knit for warm, stretchy, breathable performance. Whether you’re topping out on the Fang or running dawn patrol on Dragon’s Tail Couloir, staying warm without overheating is critical. The Nano-Air® Light Hybrid Vest traps heat at your core where you need it most but lets off steam to keep you dry and comfortable. The front of the vest warms and protects with warm-when-wet FullRange® insulation (40-g) sandwiched between a plain-weave liner and a lightweight yet durable, weather-shedding 100% nylon ripstop shell with a DWR (durable water repellent) finish. The back of the vest features a super stretchy, airy waffle knit that swiftly wicks moisture and dissipates heat. The center-front zipper has a zipper garage for comfort on the chin, and zippered handwarmer pockets rest easily under a harness or pack. Stretch binding at the armholes and hem seal in warmth.
Light yet durable 100% nylon ripstop shell and plain-weave liner offer generous mechanical stretch and exceptional breathability, with a DWR (durable water repellent) finish
