The Patagonia Women's Nano Puff® Vest is a warm, windproof, water-resistant vest made from recycled polyester. This vest provides excellent warmth for its weight and will keep you warm even when wet. It features brick quilting pattern with horizontal quilt lines on side panels that stabilizes insulation and uses durable thread for abrasion resistance. You'll enjoy the two zippered handwarmer pockets with cleanly finished zipper garages. Additionally, the internal zippered chest pocket doubles as a stuff-sack with a reinforced carabiner clip-in loop, that allows you to easily store or pack. The Patagonia Women's Nano Puff® Vest, with its drawcord-adjustable drop-tail hem, helps seal in warmth during those cold months.
