Inspired by the traditional tapered mummy bag, Soul has a sleek, streamlined shape that shaves excess material and weight wherever possible but still sneaks in plenty of comfort includes. A mono-polymer design, Soul also meets our Endless Promise® standard and can be fully recycled at the end of its life — just send it back to NEMO, and we’ll handle the rest. NEMO’s newest sleeping bag silhouette is now offered with aerospace-grade, recycled synthetic insulation for ultralight adventures in any climate.

Balancing the front zipper is a single Thermo Gill™ vent, enabling fine-tuned temperature control. With both internal plus external zippers, the Thermo Gill incrementally releases body heat without direct exposure to the cold, extending the usable temperature range of the bag. For additional instant ventilation (or simply to let your feet poke out), the footbox also offers a zippered opening. Highlighting the clean design are strategically placed vertical plus horizontal baffles to optimize warmth plus comfort while preventing migration of the Zerofiber™ 800 synthetic insulation. Soul’s single, asymmetrical front zip integrates with our innovative Headwall™ internal draft guard to give 360-degree protection. A plush, insulated collar, Headwall wraps around the back of the neck plus cozily overlaps itself in front to efficiently block cold air while creating a uniquely comfort-focused experience.
