When there's chilly air in season, and that's where the Down Sweater comes in. It delivers minimal weight, superb compressibility and high-loft warmth. The ripstop shell (1.4-oz 22-denier) with a DWR (durable water repellent) finish does more than look sharp: It's tear-resistant and windproof and made from 100% all-recycled polyester. Details include top-quality 800-fill-power goose down, an updated fit and styling, quilted-through construction, two exterior zippered pockets and a stretch-mesh interior chest pocket that doubles as a zippered stuff sack with carabiner clip-in loop.
