DESCRIPTION
Ideal for active pursuits on freezing days, this windproof insulated pant delivers warmth with breathability. WINDSTOPPER® fabrics provide complete wind and light moisture protection, and thick Coreloft™ insulation traps heat inside. New face fabric lends a supple, durable surface to the lightweight, richly radiant insulated pant. Reinforced knees and seat resist winter abrasion. Breathable fabrics work well in cold dry climates and slow-paced, steady activities and windproof fabric in the core area blocks cold air whilst lightweight insulations traps warmth inside. Cut with an expedition fit to make allowances for winter layering without restricting movement.
