Designed for high-altitude hiking and mountaineering, this packable jacket combines water-resistant goose down with lightweight 10D TORAY nylon. Box baffles at the chest and horizontal channels elsewhere support even warmth, while selected high-moisture zones blend PrimaLoft Gold insulation with down. A DWR finish helps shed light precipitation. The adjustable high-collar hood, two-way YKK zipper, knit cuffs, adjustable hem, two zippered hand pockets, and internal mesh pocket provide protection and practical storage without unnecessary bulk.
