MarmotHydrogen - Sleeping bag

The Hydrogen is a remarkably lightweight and compact sleeping bag from Marmot, offering excellent insulation for three-season hikes or treks. With a Pertex® outer shell, 800-fill power goose down insulation, and a water-resistant Down Defender treatment, the Hydrogen keeps you warm and dry throughout your night in the wilderness. After a long day of hiking in the mountains, you can rest your feet in the spacious and enveloping foot box of the Hydrogen. The multi-baffle Nautilus hood with drawcord, snag-free insulated draft tube, and two-way zipper with anti-snag slider of the Hydrogen minimize heat loss. Lastly, the Hydrogen features an internal stash pocket where you can safely store your small valuables.
