Marmot HiberNest 30 (-1C)

SKU: M16775

The Marmot HiberNest 30 is designed for outdoor enthusiasts who want the warmth and efficiency of a down sleeping bag while maintaining plenty of freedom of movement. Its roomy mummy shape provides additional space compared with a traditional mummy bag, making it comfortable for side, back and stomach sleepers.

The sleeping bag is insulated with 650+ fill-power duck down, consisting of 80% duck down and 20% duck feather. The insulation features Down Defender treatment, which helps the down resist moisture and maintain its loft and insulating performance in damp conditions.

The outer shell is made from 100% recycled nylon ripstop, offering a lightweight yet durable construction suitable for outdoor use. The lining is made from 100% recycled polyester, providing a comfortable feel while supporting the use of recycled materials. A DWR finish helps the outer fabric shed light moisture.

One of the defining features of the HiberNest 30 is its convertible design. The full-length zipper can be opened around the footbox, allowing the sleeping bag to be transformed into a spacious quilt. This provides additional versatility when relaxing at the campsite or when a more open sleeping configuration is preferred.

A built-in draft tube helps prevent warm air from escaping through the zipper area, while the internal stash pocket provides a convenient place to keep small personal items close at hand during the night.

The HiberNest 30 is designed for cool-weather camping and overnight adventures, with an ISO-rated comfort temperature of 1°C and a limit rating of -5°C. The recommended use temperature is -1°C, while the extreme rating is -21°C.

The sleeping bag comes with both a compression stuff sack and a storage sack, making it easier to transport on trips and store correctly between uses.
