The 650-fill ExpeDRY down dries quickly and stays lofty, even in damp conditions, and the wraparound footbox keeps my feet extra warm. I love the dual-zipper design for ventilation when needed, and the recycled shell fabric is a great eco-friendly touch. Whether I'm in the mountains or deep in the backcountry, this bag keeps me warm and comfortable all night." When winter nights set in, the Marmot Mad River 0 Sleeping Bag keeps us warm, dry, and comfortable through the coldest conditions.
Designed for backcountry expeditions and basecamp adventures, this mummy-style bag is packed with 650-fill-power down, offering the perfect balance of warmth and lightweight packability. Treated with ExpeDRY technology, the water-resistant down dries quickly and maintains loft, keeping us warm even in damp conditions. A full-length zipper and a secondary right-side zipper provide easy access and ventilation, while the anatomically designed footbox wraps our feet in extra warmth.
Made with 100% recycled nylon ripstop shell and lining fabrics, the Mad River 0 is as sustainable as it is reliable.
