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.
- Classic Spoon™ shape adds room at elbows and knees for versatile comfort.
- Premium 650FP hydrophobic, PFC-free, 100% RDS Certified down is traceable and ensures humane treatment throughout the supply chain.
- Waterproof/breathable footbox protects from tent condensation, keeping feet warm and dry.
- Blanket Fold™ external draft collar and a full-length draft tube provide tucked-in comfort and temperature regulation.
- Thermo Gills™ allow you to vent body heat without letting cold drafts in.
- Full-length double-slider #5 YKK zipper with zipper plow makes getting in and out of the bag a breeze.
- Integrated pillow pocket allows a jacket, extra clothes, or Fillo™ to be stuffed into the sleeve opening for secure, elevated support through the night.
- Opposite-sided zippers on Disco™ Men's and Women's models increase versatility by allowing them to be zipped together into a double sleeping bag.
