What Our Gearhead(R) Experts Are Saying:"This bag is a game-changer for ultralight backpacking. The synthetic insulation keeps me warm, even in damp conditions, and the tapered design saves weight without feeling restrictive. Plus, the draft guard and vents make it incredibly versatile in varying climates."We believe ultralight adventures shouldn't mean compromising on comfort or eco-kindness, and the Soul Sleeping Bag delivers on both fronts. This innovative sleeping bag pairs a sleek, tapered mummy silhouette with Zerofiber 800 synthetic insulation for an unbeatable combination of warmth, packability, and water resistance. Made from aerospace-grade, post-consumer recycled materials, the insulation performs in any climate-even when wet. The thoughtful details elevate our nights on the trail, from the Headwall draft guard's plush, turtleneck-inspired collar to Thermo Gill vents that allow fine-tuned temperature control without letting cold air seep in. Fully recyclable and designed to pair seamlessly with other ultralight gear, the Soul Sleeping Bag sets a new standard for efficiency and comfort in the backcountry.
