Hydrogen 30 Down Sleeping Bag

Hydrogen has the smallest atomic weight of any natural element. It's simple, abundant, and produces some of the most efficient heat in the known universe. Hydrogen helps power the very stars.

Sleep is your opportunity to recharge your batteries and restore yourself for the next day's adventure. Leaky synthetic bags don't always cut the mustard. Marmot made their Hydrogen sleeping bag with certified 850+ fill power goose down, providing the best weight to warmth ratio available on the market. Stretch tricot baffles take bag durability to the extreme — the stitches won't pull apart no matter how much you turn and stretch at night. The Nautilis 6-Baffle Hood provides six chambers of down around the head for exceptional insulation and a great fit, and the Velcro-free face muff won't claw up your chin while you catnap. A full length zipper, a trapezoidal foot box, and the Hydrogen's ultralight weight combine for a comfortable, rejuvenating journey.
