Nemo Coda Endless Promise Down Mummy Sleeping Bag

With NEMO’s signature quality and innovation, Coda™ represents a new vision of what ultralight sleeping bags can be. Inspired by the traditional tapered mummy bag, Coda has a sleek, streamlined silhouette that shaves excess material and weight wherever possible — but doesn’t stop there. A mono-polymer design, Coda also meets our Endless Promise® standard and can be fully recycled at the end of its life.

Coda’s single, asymmetrical front zip integrates with the all-new Headwall™ internal draft guard to provide 360-degree protection. A plush, insulated collar, Headwall wraps around the back of the neck and cozily overlaps itself in front to efficiently block cold air while creating a uniquely comfortable experience. Balancing the front zipper is a single Thermo Gill™ vent, enabling fine-tuned temperature control. With internal and external zippers, the Thermo Gill incrementally releases body heat without direct exposure to the cold. For additional, instant ventilation, or simply to let your feet poke out, the footbox also features a zippered opening.

Highlighting the clean design are strategically placed vertical and horizontal baffles to optimize warmth and comfort while preventing migration of the 800 FP, RDS-certified, water-resistant down. This premium down is ideal for frigid conditions and packs down incredibly small, making Coda a versatile option for both ultralight backpacking and mountaineering trips.

Manufactured from a single type of material, this sleeping bag is 100% recyclable when it can no longer be repaired or resold — just send it back to NEMO, and we’ll handle the rest.

A unisex bag, Coda calls out both the Limit temperature rating and the Comfort temperature rating in its name. Per industry standards, the Limit rating (the first number referenced in the series) is considered the benchmark for men, while the Comfort rating (the second number referenced in the series) is considered most applicable to women.
