There's much to see 14,000 feet up at the Chasm View bivy: a vertigo-inducing panorama of the Diamond and alpenglow over the Rockies. There's also chilly air in any season, and that's where our Down Sweater comes in. It delivers minimal weight, superb compressibility and high-loft warmth. The ripstop shell with a Deluge® DWR (durable water repellent) finish does more than look sharp: it's tear-resistant and windproof and made from 100% recycled polyester. Details include top-quality 800-fill-power goose down, a quilted-through construction, two exterior zippered pockets, a stretch-mesh interior chest pocket that doubles as a zippered stuff sack and a carabiner clip-in loop. Drawcord hem.
