The NEMO Equipment Riff 15 Sleeping Bag offers space-saving packability for weight-conscious side-sleepers. The Ultralight Spoon shape shaves ounces and packs down small while still offering increased room around our elbows and knees to comfortably roll over in our sleep. The hydrophobic down maintains loft on humid nights when our tent begins to fill with condensation, and the waterproof foot box and hood ensure we stay warm and dry all night long.
