With the Tracks sleeping bag line, nothing stands in the way of a hiking trip with family or friends. The Tracks sleeping bags combine functionality with sustainability and offer many practical features. Using VolumeShift, the footend can be compressed to reduce the amount of air that needs to be warmed up. In addition, the voluminous zip cover and the precisely adjustable hood protect against the cold. The practical AntiSnag slider prevents fabric snagging in the zip. The synthetic filling as well as the outer and inner fabric are made of recycled material.
