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—now with 100% 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. Fair Trade Certified sewn. The M's Nano Puff Hoody is fully backed by our Ironclad Guarantee and you can find it on Patagonia. com.
