The Men's Down Sweater Vest from Patagonia is ultralight, highly compressible, windproof, and high quaility 800-fill down insulation provides serious core warmth. This sleek vest has a minimalist design and is so compact that it stuffs into its own stretch-mesh internal pocket (with a carabiner clip-in loop). The innovative, superlight 100% all-recycled polyester shell (1.4-oz 22-denier) with a DWR (durable water repellent) finish provides wind and water protection as well as a high tear-strength; quilting stabilizes the down. With zippered handwarmer pockets and a drawcord hem.
