Seventy percent of people sleep on their side, yet mummy bags are not designed to accommodate this. Updated with new contours, Disco™ continues to reign as the ideal down backpacking bag for side-sleepers, offering the plushest comfort possible on the trail.

The classic Spoon™ shape provides a generous cut at the elbows and knees so side sleepers can shift positions comfortably throughout the night, while still packing remarkably small. Premium 650FP hydrophobic, PFC-free, RDS Certified down ensures traceability throughout the supply chain.

These 3-season backpacking bags are 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. Left-sided zippers on Men’s and right-sided zippers on Women’s allow Disco™ to zip together for a double version of these favorite sleeping bags.
