The Patagonia Men's Nano Puff Hoody handily manages all the chilly belays, melt-freeze ice couloirs, and nighttime rope-pulling epics that even the most dedicated climbers can throw at it. The Nano Puff® Hoody excels as a sleek micro-belay parka and doubles as an insulated jacket on quick alpine dashes. A simple, elasticized hood opening adds thermostat-like warmth, and the low-bulk, hydrophobic, highly compressible 60-gram PrimaLoft® Gold Insulation Eco—with 55% postconsumer recycled content—traps heat with remarkable efficiency, even when wet. The wind-blocking, moisture-shedding 100% recycled polyester ripstop shell with a DWR (durable water repellent) finish glides effortlessly in your layering system, and a soft, wicking interior storm flap and zipper garage add chin comfort (because when all hell’s breaking loose, the little things help). The hoody stuffs into an internal, zippered chest pocket that has a carabiner clip-in loop. It also has two zippered handwarmer pockets, elasticized cuffs, and a dual-adjust drawcord hem to seal out wind and seal in warmth.
