Our synthetic-fibre sleeping bag is the solution for trekkers who want both comfort and an optimum warmth-weight ratio. Chambers with elasticated seams keep the sleeping bag close to the skin, allowing for a lot of extra freedom of movement with a stretch of 25 % width wise. At the same time, it heats up quickly since the sleeper has to warm up very little air. The 360-degree filling guarantees freedom of movement when sleeping, eliminating the fear of freezing. The contour-feature hood reliably surrounds the head, the raised foot area adjusts perfectly to the shape of the feet. New materials ensure a pleasant and almost crackle-free sleeping environment.
