Nemo's Riff 30F offers a lightweight package of spaciousness, premium materials, and warmth. Its Spoon shape provides freedom of movement for side sleepers, while 800-fill hydrophobic down insulates to a -1 °C rating. The ThermoGill venting system and Blanket Fold draft collar help regulate temperature. The waterproof foot box, recycled materials, and anti-snag zips enhance durability. The Riff 30F is ideal for active side sleepers seeking comfort and warmth on three-season trips.
Nemo says:
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.
Our Verdict
For discerning backpackers who toss and turn at night, Nemo's Riff 30F provides a luxurious combination of roominess, premium materials, and warmth in a svelte package. The key is Nemo's ultralight Spoon shape with extra girth around the elbows and knees, which allows side sleepers to shift positions freely without feeling constricted.
At its core, top-quality 800-fill hydrophobic down provides furnace-level warmth to the 30°F rating. Nemo's ThermoGill venting system offers extra ventilation options through double zippers without compromising warmth—the plush Blanket Fold draft collar seals in heat around your shoulders.
Other highlights include a waterproof/breathable foot box, ultralight 20D recycled ripstop fabrics with PFC-free DWR, and anti-snag zip tracks. Weighing under 2 lbs for the regular, it's an exceptionally lightweight option for weight-conscious adventures.
Perfect for active side sleepers, the Riff 30F delivers Nemo's legendary spacious sleep comfort with premium 800-fill-down insulation. It is an excellent investment for backpackers wanting a warm, ultralight sleeping oasis without feeling confined on three-season trips.
