Nemo’s newest sleeping bag silhouette is now offered with aerospace-grade, recycled synthetic insulation for ultralight adventures in any climate.
Inspired by the traditional tapered mummy bag, the Soul Endless Promise Synthetic Mummy Sleeping Bag has a sleek, streamlined shape that shaves excess material and weight wherever possible but still sneaks in plenty of comfort features. A mono-polymer design, Soul also meets the Endless Promise® standard and can be fully recycled at the end of its life-just send it back to Nemo. Soul’s single, asymmetrical front zip integrates with the innovative 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. For additional instant ventilation, 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 Zerofiber™ 800 synthetic insulation.
