The DEFENCE 4 is the most popular and best-selling all-round sleeping bag with excellent weight to stuff size and performance ratio. It is a well-established, threeseason sleeping bag that has proven to be 100% reliable on cold nights both in the wilderness and in snow caves. 

A protection flap on the outer side of the zipper keeps out wind and wetness. The outer shell is a super-light, highly resistant, microfibre nylon with a fine microporous coating which makes it waterproof. There is a generous draft tube on the inside of the zipper to prevent heat loss at the zipper.
