Big and warm just like the prehistoric creatures that used to roam the earth, the Domex Mammoth will keep you comfortable down to -10°C. This semi-rectangular bag is 90cm at the shoulder so you can easily get into that perfect sleeping position without feeling restricted. Box wall construction keeps the bags 1000g of Grey Duck 90/10 down evenly distributed through the length of the bag and prevents any clumping and cool spots.   

YKK zip stretches the entire length of the bag from the shoulder to the bottom of your sleeping bag, simply unzip the bag all the way to the foot and open the bag for easy entry. If you like a palatial bag that is comfy and warm the Mammoth is the bag for you.
