Deuter Exosphere -6° - Deuter's PFC-free synthetic fiber sleeping bag is the solution for trekkers looking for comfort and an optimal warmth-to-weight ratio. Elastic chamber seams keep the synthetic fiber sleeping bag close to the body. It can be stretched by 25% in width. This offers a lot of freedom of movement and at the same time it warms up quickly because the sleeper doesn't have to warm up much air. The innovative contour function hood reliably envelops the head, the raised, diagonally cut foot area adapts perfectly.
