The Patagonia Nano Puff® Jacket finds a home with any climber adventurer. Its wind-blocking, 100% recycled polyester shell sheds moisture and glides effortlessly within your layering system. Low-bulk, hydrophobic, highly compressible 60-g PrimaLoft® Gold Insulation Eco—with 55% post-consumer 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. An internal zippered chest pocket doubles as a self-stuffsack with a carabiner clip-in loop. Details include a pair of zippered hand-warmer pockets, elasticised cuffs and a single-adjust drawcord hem to seal out wind and seal in the warmth.
