Marmot HiberNest 15 Sleeping Bag: 15F Down Summer Storm/Thunderhead, Reg/Left Zip

What Our Gearhead® Experts Are Saying:“I like this sleeping bag for how comfortable it is in real use. The zipper opens wide like a quilt, the draft tubes work well, and the recycled fabrics feel soft—not crunchy. It’s a warm, dependable bag that suits side sleepers, too.”We reach for the HiberNest 15 Sleeping Bag when comfort ranks just as high as warmth on backcountry nights. Its expansive zipper configuration opens flat like a quilt, creating a roomy, adaptable space whether we stretch out, curl up, or shift positions through the night. Certified 650+ fill power down provides reliable loft and compressibility, while Down Defender treatment keeps the insulation performing in damp or variable conditions. Soft recycled liner fabric welcomes us after long days on the trail, and thoughtful features—like a pillow pocket, internal stash pocket, and full-length draft tube—help settle us into deeper, warmer sleep. ISO-rated performance builds confidence across changing temperatures, and the included compression sack simplifies packing between campsites. Offered in Short, Regular, and Long lengths, the HiberNest 15 Sleeping Bag ensures a comfortable, dialed fit for a wide range of backpackers.
