Couloir Sleeping Bag: 0 Degree Down

Youll appreciate the warmth and water-resistance of the Marmot Couloir 0-Degree Down Sleeping Bag when youre sleeping comfortably though a harsh winter storm. Thanks to its 800 fill goose down and DWR coated nylon shell, the Couloir is perfect for winter camping and mountaineering. Its down-filled draft collar seals in the warmth, and ground-level seams eliminate cold spots. Marmot also gave the Couloir a large foot box, so you never wake up with cold, cramped feet.
