Our Nano Puff® Hoody handily manages all the chilly belays and nighttime rope-pulling sessions that a climber can throw at it. It 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-g 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. 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.
