Overview

A pinnacle-performance 3-season 800 FP down bag, Riff™ offers a trim, athletic cut designed for side sleepers who crave space-saving packability. NEMO’s iconic Spoon® bags are cut wider at the elbows and knees so campers can easily shift positions throughout the night, and the Ultralight Spoon silhouette used on Riff maintains that extra room while cutting in tighter at the feet and shoulders. The result is a sleeping bag vastly more comfortable than a mummy bag, but still impressively compact.

Riff includes a set of next-generation Thermo Gill™ vents on the chest to offer fine-tuned temperature control and a better outdoor sleeping experience. Each Gill features an interior and an exterior zipper with a draft-blocking intermediate layer, allowing several different configurations for dialing in the bag’s temperature without direct exposure to cold air. Our Blanket Fold™ draft collar at the neckline features a redesigned size and shape to further optimize sleep temperature. Tucked in, the Blanket Fold defiantly blocks any chill while mimicking the comfort of your bed at home. Pushed out, it helps dump excess heat instantly. Finally, Riff includes strategically designed baffles insulated with water-resistant, RDS-certified down that are placed vertically along the torso for comfort and aligned horizontally below the waist to prevent down migration.

Riff™ is NEMO’s top-of-the-line, backcountry-oriented sleeping bag — and it’s also the latest addition to our suite of Endless Promise® products. Manufactured from a single type of material, this sleeping bag is 100% recyclable at the end of its life — just send it back to NEMO, and we’ll handle the rest.
