The perfect warmth for just about everything, Patagonia's classic Men's Down Sweater Vest is lightweight and windproof with a 100% recycled polyester ripstop shell and 800-fill-power Advanced Global Traceable Down (goose down certified by NSF International from parent farm to apparel factory to help ensure that the birds that supply it are not force-fed or live-plucked). Worth its weight in gold when the sun dips below the horizon, the Patagonia Men's  Down Sweater Vest keeps its focus simple: core warmth. It traps your hard-earned heat with high-loft, 800-fill-power Advanced Global Traceable Down (goose down certified by NSF International, traced from parent farm to apparel factory to help ensure that the birds are not force-fed or live-plucked) and its minimalist design practically floats—it’s so compact that it stuffs into an internal pocket (with a carabiner clip-in loop). The 100% recycled polyester shell with a DWR (durable water repellent) finish provides wind and weather protection, while quilting lines stabilize the down. The drawcord hem tightens from inside the zippered handwarmer pockets, and nylon-bound elastic armholes seal in heat.
