Purchase thru Marmot

The Marmot HiberNest Down 30° Long Sleeping Bag is a super-wide mummy bag built for side, back, and stomach sleepers who want room to roll over without wrestling the walls. Its 650 fill power duck down carries a Down Defender water-resistant treatment that helps prevent clumping, so the bag keeps its loft and dries quickly in damp, humid conditions, while the 100% recycled shell and lining add durability without extra weight.

Unzip the main and side zippers all the way and the bag opens into a quilt with extended blanket flaps, turning a tent, hut, or van night into something closer to home. A draft tube seals in warmth, an internal stash pocket keeps a phone or watch close at hand, and the included compression sack and storage bag make packing small and storing right. ISO tested for a reliable temperature rating, it comes in a gender-free design and is available in standard, short, and long sizes.
