Riff is NEMO’s top-of-the-line, backcountry-oriented Ultralight Spoon™ shape sleeping bag. This pinnacle performance 3-season 800 FP down bag offers a more athletic cut, designed for side sleepers who prefer space-saving packability and shaving critical ounces for long hours on the trail.
Seventy percent of people sleep on their side, yet mummy bags are not designed to accommodate this. NEMO’s unique Spoon shape bags offer more room at the elbows and knees, allowing side sleepers to shift positions comfortably throughout the night.
This popular bag is loaded with features, including Thermo Gill™ vents that help regulate temperature during the night, a Blanket Fold™ draft collar that provides tucked-in comfort, and a waterproof/breathable footbox to withstand tent condensation. Left-sided zippers on the men’s and right-sided zippers on the women’s bags allow two Riffs to zip together for a double bag.
