Mountain Hardwear down jacket

Woven entirely from a single stretch fabric, including down-filled compartments, the Stretchdown™ model will provide warmth and freedom of movement during all your winter activities. The dense fabric, made from a soft, abrasion-resistant, tear-resistant blend of materials, stretches when you move and blocks out the cold while allowing excess moisture and heat to escape. Whether climbing, belaying or under a waterproof jacket, this top will keep you moving in comfort.
