Born of shoulder-season belay duty and springtime ski tours, the Nano Puff Jacket from Patagonia finds a home with any alpine climber or backcountry skier. Its wind-blocking, 100% recycled polyester shell sheds moisture and glides effortlessly in your layering system. Low-bulk, hydrophobic, highly compressible PrimaLoft® Gold insulation (60-g) traps heat with remarkable efficiency, even when wet. Nano Puff 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. Its internal zippered chest pocket doubles as a self-stuffsack with 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.\n\nWind- and water resistantPrimaLoft Gold 60g insulation keeps the jacket warm even when wetAdjustable hemInternal chest pocket doubles as a stuffsack with a carabiner clip-in loopShell and lining: 1.4-oz 22-denier 100% recycled polyester with a DWR (durable water repellent) finishFabric is certified as bluesign® approvedInsulation: 60-g PrimaLoft® Gold Insulation Eco 100% polyester (55% postconsumer recycled content)Fabric: 100% PolyesterLining: 100% Polyester Patagonia Men's Nano Puff Jacket Andes Blue | Buy Patagonia Men's Nano Puff Jacket Andes Blue here | Outnorth
