Patagonia Women's Nano Puff Vest Black Sz S Warm, windproof, water-resistant—the Nano Puff® Vest uses incredibly lightweight and highly compressible. This is a versatile classic that you will probably wear all winter long. I was always a fan of this style because it is warm yet it doesn't' make you look like the marshmallow man. Very flattering.
