The Helium Sleeping Bag is lightweight enough for long stretches on the trail and roomy enough to sleep comfortably under the stars. Certified 800-fill-power-down and a Pertex® Quantum shell team up for warmth and weather protection. Curved baffles keep the insulation in place, while the multi-baffle hood maximizes coziness where it matters. After a long day on your feet, tuck them into the footbox, catch some zzz’s, then do it all again tomorrow.
