Our Down Sweater's featherweight, superbly compressible warmth protects from seasonal chill. The 100% polyester ripstop shell sheds snow and wind. The 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) remains stabilized with quilted-through construction and a contoured fit; a drawcord hem tightens from inside the zippered handwarmer pockets and an interior chest pocket doubles as a zippered stuffsack with a carabiner clip-in loop. Nylon-bound elastic cuffs seal in heat, and the DWR (durable water repellent) finish sheds moisture.
