The Women's Patagonia Nano Puff Hoody is a lightweight insulation piece for cool to cold weather activity and layering. Insulated with 60-g PrimaLoft Gold Insulation Eco, it offers excellent warmth for the weight and retains heat even when wet. The brick quilting pattern with narrow horizontal lines on the side panels helps stabilize insulation and adds abrasion resistance. A center-front zipper includes a wicking interior storm flap and a zipper garage at the chin for enhanced comfort. Two zippered handwarmer pockets have neatly finished zipper garages, and an internal zippered chest pocket doubles as a stuff sack with a reinforced carabiner clip-in loop. The hood is designed to fit under a helmet, and a drawcord-adjustable drop-tail hem seals in warmth.
