Intelligently designed to keep yurt-loving tourers, side sleepers, and fringe-season backpackers warm.

Get some well-deserved rest on your next yurt tour or backcountry trip with the MontBell U.L. Super Spiral Hugger #1 Sleeping Bag. Premium 800-fill goose down inside this bag's innovative stretch baffles hugs you close and insulates you from the cold's prying fingers. With advanced cold-fighting features like a double insulated draft tube, draft collar, and adjustable hood, you can stay toasty in a drafty yurt while you dream of the pow day to follow.
