Marmot Atom 40F Down Sleeping Bag - Regular Size

The Marmot Atom 40F Down Sleeping Bag is your best companion this summer on your alpine trips when you need a reliable bivy. Featuring 800 fill power goose down treated with Down Defender for water resistance and to keep you warm on cool summer evenings, the Atom 40F Down Sleeping Bag has smooth-curved baffles that reduce shifting of down to eliminate cold spots. The multi-baffle hood helps keep your body heat in so you're warmer over night, and you'll also stay warmer thanks to the warp-around footbox that's anatomically designed for your comfort. A fold-down second zipper lets you adjust your ventilation and helps provide easy access, while an anti-snag zipper reduces snagging, making it easy to get in and out of the Atom 40F Down Sleeping Bag. And the snagless insulated draft tube, two-way zipper sliders with zipper garage, and a hood draw cord make the Atom 40F Down Sleeping Bag ultra comfortable and convenient for days on the trail. An internal stash pocket ensures your smartphone stays close, and two hang loops give you options for stashing your bag.
