Disco 15 Endless Promise Down Sleeping Bag 15F / -9C (Women's)


SKU: 301461

The reigning favorite down bag for backpackers, Disco™ features the best-of-all-worlds Classic Spoon® silhouette for ultimate side-sleeping comfort.

NEMO’s iconic Spoon bags are cut generously at the elbows and knees so campers can shift positions comfortably throughout the night, but shave unnecessary weight so gear still packs up light. The Classic Spoon is the sweet spot of the line, balancing packability with plush, roomy comfort.

Disco includes a set of next-generation Thermo Gill™ vents on the chest to offer fine-tuned temperature control and a better outdoor sleeping experience. Each Gill features an interior and an exterior zipper with a draft-blocking intermediate layer, allowing several different configurations for dialing in the bag’s temperature without direct exposure to cold air. Our Blanket Fold™ draft collar at the neckline features a redesigned size and shape to further optimize sleep temperature. Tucked in, the Blanket Fold defiantly blocks any chill while mimicking the comfort of your bed at home. Pushed out, it helps dump excess heat instantly. Finally, Disco’s revamped design has baffles insulated with water-resistant, RDS-certified down, placed vertically along the torso for comfort and aligned horizontally below the waist to prevent down migration.

Along with this suite of top features, Disco now boasts the purpose-driven Endless Promise® designation, meaning it was designed specifically to stay out of the landfill and on the trail, forever. With a shell manufactured fully from PET, this sleeping bag is 100% recyclable at the end of its life — just send it back to NEMO, and we’ll handle the rest.


  • Classic Spoon® shape adds room at elbows and knees for versatile comfort.

  • Updated Thermo Gill™ vents extend the comfort range and create fine-tuned control with their multistage zipper system.
