The Marmot Atom 40-Degree Down Sleeping Bag relies on high-loft, premium-quality 850-fill goose down for its incredible warmth-to-weight ratio. An ultralight ripstop shell holds the insulation in place without adding much weight or bulk for easier compressibility. Take the Atom along on your next summer backpacking trip—it's so compact and lightweight, you'll have no trouble finding space for it in your pack.
