Windproof and water-resistant, the full-zip Nano Puff Hoody is made with warm, incredibly lightweight, highly compressible PrimaLoft One insulation. Ideal as an insulating layer or outerwear in cold climates.

When missing the sunset curfew means climbing through spindrift rivers into the night, the Nano Puff Hoody shines. It is windproof and weather-resistant enough to wear as an insulated jacket in a sudden squall, trim enough to pull on for chilly rock pitches (and still see your footholds) and warm enough for light belay parka duty on quick alpine dashes, or for climbing through the night when the dash isn't so quick. The elasticized hood opening snugs over low-volume helmets or under any helmet, adding thermostat-like warmth. The wind-blocking, moisture-shedding 100% recycled polyester shell glides effortlessly in your layering system, and low-bulk, hydrophobic, highly compressible PrimaLoft One (60-g) traps heat with remarkable efficiency, even when wet. The hoody packs down to practically nothing and 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.
