Mammut

Altitude Down Winter Sleeping Bag: -8F Down

You can rely on Mammut's Altitude Down Winter Sleeping Bag when nighttime temperatures dip below zero and you have a snowy, winter wonderland to explore just outside the tent. Mammut fabricated it for rowdy expeditions, with a waterproof, breathable shelterTX membrane and durable nylon fabrics to fend off winter's wrath. For warmth, Mammut stuffed the Altitude in the lightest, loftiest, most packable down insulation that the Mammoth-branded company has to offer. There's a removable, fleece lining near the foot section because toes are generally the first to go when it comes to frostbite.
