Riff 15 Endless Promise Goodnight Gray

NEMO's iconic Riff™ bags are wider at the elbows and knees so campers can easily change position throughout the night, and the Ultralight Spoon silhouette used on the Riff maintains that extra space while being more fitted at the feet and shoulders.

The result is a sleeping bag that is much more comfortable than a mummy bag, but still incredibly compact. The Riff features a next-generation Thermo Gill™ vent system on the chest for precise temperature control and a better outdoor sleeping experience.

Each Gill features inner and outer zippers with a windproof intermediate layer, allowing several different configurations to regulate the bag's temperature without direct exposure to cold air.

Our noise-free Blanket Fold™ collar at the neck features a redesigned size and shape to further optimize sleep temperature. Tucked inward, the Blanket Fold boldly blocks out the cold while mimicking the comfort of your bed at home.

Pushed outward, it helps instantly vent excess heat. Finally, the Riff features strategically designed baffles, insulated with RDS-certified water-resistant down, placed vertically along the torso for added comfort and aligned horizontally below the waist to prevent down migration.

The Riff™ is NEMO's premium backcountry sleeping bag — and it's also the latest addition to our Endless Promise® product line. Made from a single type of material, this sleeping bag is 100% recyclable at end of life: simply send it back to NEMO and we'll take care of the rest.
