NEMO Riff Endless Promise Down Sleeping Bag

The NEMO Riff is an 800-fill-power, RDS-certified down sleeping bag built for backcountry use across three seasons. It uses NEMO's Ultralight Spoon silhouette, which is cut wider at the elbows and knees than a standard mummy bag to accommodate side sleepers and position changes through the night, while tapering more closely at the feet and shoulders to reduce bulk. The shell and insulation are manufactured from a single material type, making the bag 100% recyclable through NEMO's take-back program at end of life. It is available in 15°F and 30°F temperature ratings and Regular or Long lengths.

Features

• Thermo Gill vents: Chest vents each carry an interior zipper, an exterior zipper, and a draft-blocking intermediate layer, allowing staged ventilation without direct cold-air exposure.
• Blanket Fold draft collar: An oversized collar at the neckline tucks in to block cold air or folds out to release excess heat.
• 800 FP hydrophobic down: Fill is PFAS-free and certified to the Responsible Down Standard, which requires animal welfare compliance at the farm level.
• Waterproof hood and footbox: Both zones are reinforced with recyclable waterproof material to resist tent condensation.
• Vertical and horizontal baffles: Baffles run vertically along the torso for comfort and horizontally below the waist to limit down migration.
• Couple compatible: Two Riff bags with opposing zipper sides can be zipped together to form a double bag.
