For mountaineers and trekkers looking for maximum insulation at minimal weight for extreme conditions. The lightweight Astro Pro down sleeping bag is a bluesign® certified product manufactured to strict environmental and social standards, with minimal impact on people or planet – so you can enjoy a good night’s sleep with a clear conscience. Deuter also only uses down that carries the Responsible Down Standard (RDS). The liner stretches by up to 25% across the width for unrestricted movement and fewer air pockets inside the sleeping bag that require warming. The more sensitive foot zone is also given extra space in a 3D ergonomic footbox for superior insulation. The lightweight compression sack with new lateral compression means the bag packs down so small it easily stows in any pack. In order to care for the down, we recommend you store your sleeping bag loose in the mesh storage sack. deuter - Astro Pro 600 SL Down Sleeping Bag Women paprika redwood
