Camping on the slopes of Mount Cook in the middle of winter or taking on one of the highest peaks in the Himalaya or Andes is going to call for a seriously warm alpine style sleeping bag. Enter the Sea to Summit Alpine ApIII Sleeping Bag which sports an EN comfort rating of -12°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 ApIII a serious high-altitude bag. 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. 

This is one of the warmest sleeping bags in the Snowys range and is aimed at the serious cross-country skier, mountaineer, and alpine climber.
