Built to conquer freezing conditions without the bulk, the Thorium Hoody pairs high-loft 750 fill-power goose down with strategic Coreloft™ insulation to keep you warm even in damp weather. The lightweight Arato™ 30 nylon shell repels wind and moisture, while the insulated StormHood™ locks in critical body heat during high-elevation treks. It’s a go-to versatile layer for cold-weather hikes, backcountry ascents, or frigid alpine mornings.
