Product Details

Seventy percent of people sleep on their side, but mummy bags are not designed to accommodate this. With a unique Spoon™ shape adding room at the elbows and knees, the Riff™ is a three-season down men’s backpacking bag that is designed for side sleepers, and allows you to shift positions throughout the night.

This popular bag is loaded with features, including Thermo Gills™ that help regulate temperature during the night, Blanket Fold™ that provides tucked-in comfort, and a waterproof/breathable footbox to withstand tent condensation. Zip together with the women's Jam for a double bag. This bag is a versatile superstar for everything from backpacking to car camping.
