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, but there’s also chilly air in any season … that’s where our Down Sweater comes in. It delivers minimal weight, superb compressibility and high-loft warmth. The polyester shell does more than look sharp: It’s tear-resistant, windproof and water-repellent, and made from 100% recycled polyester. Details include top-quality European 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.
