Born of shoulder-season belay duty and quick-hit ski tours, the Nano Puff Jacket finds a home with any back-country aficionado. Its wind-blocking, 100% recycled polyester shell sheds moisture and glides effortlessly in your layering system. 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 jacket has a sculpted fit, with narrow, horizontal quilting on the shaped side panels, and the soft, wicking interior storm flap and zipper garage add chin comfort. An internal zippered chest pocket doubles as a self-stuffsack with a carabiner clip-in loop. Details include a pair of zippered handwarmer pockets, elasticized cuffs and a single-adjust drawcord hem to seal out wind and seal in warmth. Fair Trade Certified sewn.
