The Defense 4 comes from the military sector and is one of the best-selling 3-season sleeping bags in its class. It is characterized by the center zipper and an extremely robust and waterproof outer material. The zippered cover flap protects against wind and moisture and the integrated zipper warming strip additionally prevents heat loss. The outer shell is a super-light, highly resistant, microfibre nylon with a fine microporous coating which makes it water-repellent. There is a generous draft tube on the inside of the zipper to prevent heat loss at the zipper.
