Deuter Astro Pro 400 SL

The Deuter Astro Pro series sleeping bags are designed for hikers, climbers, bicycle tourers and other activities. The materials are of high quality, and very light weight. The flexible lining of the sleeping bag fits snugly around you and can expand by 25% – preventing cold air pockets from forming inside the bag.

This version, updated for spring 2026, is different from the previous ones: the down is now of higher quality (FP750 vs 650), the fabrics are lighter and there is moisture-repellent fabric in areas that are prone to moisture. The weight has dropped and the pack size has decreased, but the bag is also a couple of degrees warmer than before!
