The Disco Endless Promise is NEMO's 30°F down backpacking bag built around the Spoon shape, which is wider at the shoulders and knees so side sleepers can bend their legs without compressing the insulation. It uses 650-fill RDS-certified down in a recycled PET shell, weighs about 2 lb 4 oz packed in Regular, and adds Thermo Gills for venting, a draft collar, a pillow pocket and a 3D footbox. The Endless Promise label means NEMO takes the bag back for full recycling at end of life. It suits side sleepers and three-season campers who value room and comfort over the lowest possible weight; lighter mummy bags beat it on pack size, and its 650-fill down is less efficient than the 800-fill used in pricier ultralight bags.
