More comfy than a mummy bag, but still very light and compact, the women's NEMO Riff 15 Endless Promise down sleeping bag is cut wider at the elbows and knees so you can easily shift positions.
- Updated Thermo Gill vents on the chest offer fine-tuned temperature control and a better outdoor sleeping experience
- Each Gill has interior and exterior zippers with a draft-blocking layer, allowing different configurations for dialing in comfort without direct exposure to cold air
- Blanket Fold draft collar at the neckline features a redesigned size and shape to further optimize sleep temperature
- Tucked in, the Blanket Fold blocks any chill while mimicking the comfort of your bed at home; pushed out, it helps dump excess heat instantly
- Filled with premium 800-fill-power, hydrophobic, PFAS-free down
- Responsible Down Standard (RDS)–certified down; products certified to the RDS contain down or feathers from farms certified to animal welfare requirements
- Revamped design has baffles insulated with water-resistant down placed vertically along the torso for comfort
- Baffles are aligned horizontally below the waist to prevent down migration
- Hood and footbox are reinforced with recyclable material treated with PFAS-free waterproofing to prevent tent condensation from soaking into the bag's fabric
- Body-mapped design includes 3D footbox for tailored comfort and warmth
- Ultralight Spoon shape adds room at elbows and knees yet is tailored for weight-shaving warmth
- Zipper together 2 Riff sleeping bags with opposing zipper sides to create a double sleeping bag
- NEMO takes full responsibility for all Endless Promise® products, from production to end of life, and designs them for 100% recyclability to keep them out of the landfill
- Manufactured from a single type of material, this sleeping bag is 100% recyclable at the end of its life—just send it back to NEMO
- Protected by the NEMO Lifetime Warranty

Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.
