Back to TopBELOW-ZERO EXPEDITION SLEEPING BAGSAlpine expeditions require you to be prepared, focused, brazen, and safe. For the longest nights perched on the side of a glacial peak, shop our expedition sleeping bags.
Rated for conditions as low as -40° F, they’re constructed with premium, water-resistant down or synthetic insulation that straddles the line between ultra-warm and super lightweight. A non-bulky mummy-style design keeps unneeded corners from overloading your pack, keeping you agile as you ascend.
To get the most out of your gear, get a waterproof sleeping bag. Part of our pinnacle level of equipment, these bags made for elite climbers in extreme conditions. Q.Shield DOWN 800-fill repels moisture for minimum clumping, allowing the feathers to keep their loft, thus keep warmth from escaping and cold from breaking in. A hidden baffle construction takes it to the next level. And, the Dry.Q shell battles melting snow and condensation.
At a more democratic level are our sleeping bags rated at 0° F. With a dense weave and synthetic insulation, they’re ideal for camping and backpacking. Made with the spirit of mountaineering, they feature must-have details like a comfort footbox, face gasket to block drafts at the hood, and single-handed drawcords so you can get in fast and easily.
For more options, check out our general cold-weather sleeping bags or camping sleeping bags. For basecamps, add another layer of warmth and cushion with our quilts. Set up camp with our expedition tents and browse our full collection of premium outdoor equipment.
