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 move. Its 650 fill power duck down is treated with Down Defender to resist clumping and dry quickly in damp conditions, while the 100% recycled shell and lining keep weight low. Unzip the main and side zippers all the way and the bag converts into a quilt with extended blanket flaps for a more open, home-like feel.

An internal stash pocket keeps a phone or watch within reach, and the draft tube seals in warmth when you shift during sleep. The bag is ISO tested for a reliable temperature rating and comes with a compression sack and storage bag. It is available in standard, short, and long sizes with a gender-free design.
