For deep winter missions in exposed terrain, the Western Mountaineering Bison StormShield Sleeping Bag -40°C offers outstanding insulation with the weather resistance needed for demanding mountain and polar conditions. The roomy mummy shape is paired with a full collar for added thermal efficiency, while the abrasion-resistant footbox lining is well suited to rough use and storing heavier alpine gear. Despite its extreme warmth, it still packs into an included stuff sack for transport between camps, making it a strong choice for remote expeditions where every piece of gear needs to perform.
