Quick overview

The Deuter Astro Pro 400 professional down sleeping bag is perfect for mountaineers, both in the tent and under the stars. The inner lining, which can stretch 25% in width, fits perfectly around the sleeper. It offers plenty of space and at the same time keeps the sleeping bag warm. The sensitive foot area is optimally insulated by the three-dimensional foot box and the ergonomic cut guarantees pleasant foot freedom.


Warm and cozy with the 360 fill system
The 360° fill system with the same amount of fill and same construction top and bottom means the temperature rating in the Deuter sleeping bags is guaranteed in all sleeping positions.

The lightweight Astro down sleeping bag is a bluesign® 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. 

Compact stuff sack
The lightweight compression stuff sack with new lateral compression means the bag packs down small to stow inside a pack. However, we recommend storing your sleeping bag loose in the mesh storage sack.

Roomy and warm
The lining stretches up to 25% widthwise, hugging the shape of your body. It gives this bag a spacious feel while trapping warmth inside the bag. A three-dimensional, ergonomic footbox provides superior insulation in the sensitive area around the feet, with plenty of room to move around.
