Powerful warmth in a light, packable layer, the Patagonia Down Sweater is the modern standard for alpine missions and extreme weather anywhere. The weather-resistant outer fabric is extremely light and has a good amount of abrasion resistance. The Traceable down is third-party certified to be non-live plucked and supplied from a facility that does not practice force feeding. Quilted construction keeps the down in place and the clean design is roomy enough for added base layers. Shell is recycled polyester ripstop with a DWR finish to keep it water-resistant and windproof. Lining is polyester plain weave with a DWR finish. Insulated with high-loft premium traceable goose down. Sewn through quilted construction. Full-length, lightweight Vislon zipper. 2 zippered hand pockets. Internal pocket has a carabiner clip and doubles as the jacket's stuff sack. Nylon-bound elastic cuffs keep the cold away from wrists. Drawcord hem seals out drafts.
