Western Mountaineering Bison StormShield Sleeping Bag

When pushing for a serious, grit-testing summit, a good night's sleep is one of many things that can set us up for success. The Western Mountaineering Bison StormShield Sleeping Bag helps us get those restorative Zs despite the mountain's howling winds and icy temps. The featherweight construction with 850+ fill down can compress to stash away in a pack when making our way to the upper base camp. When we crawl inside this bag at the end of the day, the breathable GORE-TEX INFINIUM fabric shuts out condensation to protect the lofty insulation, ensuring no cold spots form, while the V-Block side baffles, interlocking draft tubes, and the hood's integral ruff stop numbing temps from finding another way inside. Lined with an abrasion-resistant material, the footbox stashes our boots, so our toes can start the day off cozy.
