Dawn in the desert and dusk in the mountains share at least one thing: cold. This functional, hooded pullover is pared down, super light and made with top-quality European goose down for chilly belays and frigid bivies. The quilted-through construction holds the down in place, and the highly tear-resistant recycled polyester shell fabric resists wind and repels water. A deep main zipper ventilates and allows easy on/off with a helmet; the hood is helmet-compatible; and the pass-through handwarmer pockets have a zippered kangaroo pouch that doubles as a stuff sack.
