The shell also blocks the wind and repels water. 850 fill European goose down is packed into a technical hood, a draft collar and an an oversized draft tube, and offset baffles work with the mummy cut to keep you warm in the most drastic winter temperatures. With a good sleeping pad and a bag like this, you'll get the rest you need before pushing to the summit!
