Camping in snowy, winter conditions, or in an alpine environment requires a serious sleeping bag. A bag that has the ability to cinch in every molecule of warmth to keep you comfortable. Enter the Sea to Summit Alpine ApII Sleeping Bag which sports an EN comfort rating of -8°C. 

A 3D NanoShell keeps the 850+ Loft ULTRA-DRY premium goose down dry and ready to loft up when you need it most. A contoured mummy design, offset baffles, 60/40 fill ratio, and an oversized neck collar and hood seal make the Alpine ApII a serious high-altitude bag, whether you're climbing Mount Cook in spring, or trekking to Everest Base Camp. Other features include an anatomically shaped box foot for comfort and an internal security pocket to keep devices, like a digital camera, secure and warm so they can perform in the cold. 

Not the smallest or lightest bag in the Sea to Summit sleeping bag range, but a must-have for the serious winter or alpine camper.
