Marmot Helium Sleeping Bag, Long

Refuel on your next below-freezing backpacking adventure in the ultralight, eco-friendly Helium 15 degrees Sleeping Bag, featuring a new sustainable ExpeDry water-repellent technology that increases performance and reduces the drying time of your down bag. With an optimal ISO-tested comfort well below freezing, the Helium will keep you toasty from head to toe in a super-packable 800-fill-power down bag designed to easily stuff into any overnight pack. A thru-hiking favorite, the new gas bags provide lightweight warmth that’s light on the Earth – perfect when you’re looking to maximize miles or speed in the mountains and minimize weight and space in your pack. If going tent-less is in the plan, you can count on the quick-drying ExpeDry to perform as a bivvy sack on cold, wet, or snowy ground or ledges.
