Whether you’re swinging for Steelhead on the Peninsula or throwing Blue Wings on the Yak in October, Patagonia’s Nano Puff Jacket traps your heat and blocks the wind. The 100% recycled polyester shell sheds moisture and fits effortlessly in your layering system, while the low-bulk, hydrophobic, highly compressible 60-g PrimaLoft® Gold Insulation Eco—with 55% postconsumer recycled content—warms with remarkable efficiency, even when wet. The shape is sculpted with narrow horizontal quilting on the side panels, and the soft, wicking interior storm flap and zipper garage add chin comfort. The internal zippered chest pocket doubles as a self-stuffsack with a carabiner clip-in loop. Details include two zippered handwarmer pockets, elasticized cuffs and a dual-adjust drawcord hem to seal out wind and seal in warmth. Fair Trade Certified™ sewn.
