Product Highlights

Compact and weighing less than 2 lbs, the Marmot Hydrogen 30 Degree sleeping bag is an ideal choice for high-performance backpacking in late spring, early fall or summer. An array of features and 850+ fill down insulation make the Hydrogen 30 Degree ready for backcountry adventure.

The Hydrogen 30 Degree is insulated with certified 850+ fill goose down. Fill power measures the loft or "fluffiness" of down insulation and Marmot goes to great lengths to guarantee the 850+ certification with a battery of in-house and external verifications. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet; this is less of a problem in the Hydrogen 30 Degree, though, since the down in this bag is protected with Marmot’s Down Defender water repellent treatment that allows the down to stay drier 10 times longer than untreated down in damp conditions. Down Defender down also Maintains 150% more loft and dries 30% faster than untreated down.

Despite its lightweight construction, the Hydrogen 30 Degree makes no sacrifice with regards to performance and features. Eliminating cold spots and providing comfort, sewn-through baffles ensure that the Hydrogen 30 Degree's insulation is distributed evenly throughout the bag. The Nautilus 3D contoured, ergonomic hood mirrors the design of Marmot's popular outerwear jackets, helps reduce heat loss and keeps your head warm and comfortable. An insulated oversized draft tube sewn behind the full-length zipper keeps cold air from reaching the inside of the sleeping bag and zipper guards help to avoid irritating and damaging snags. Marmot's patented Trapezoid Foot Box is wider at the toes and narrower at the heels, providing a more natural fit and improving warmth and comfort.

Filled and finished in the USA (Rohnert Park, CA), the Marmot Hydrogen 30 Degree sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") lengths. A stuff and storage sack is included.

Styles available: Long, Regular

    Likes: This bag is very light especially compared to my old synthetic bag. I like that it is very compressable. So much so that it seems to disapeer in my 60L pack. I have not used it in the field yet so I don't know how the DWR coating of the shell and the down will hold up.

    Dislikes: The zipper can snag on the shell and linning material quite easily. Just need to take the time to zip it up.
