Our professional down sleeping bag Astro Pro is perfect for mountaineers, whether in a tent or under the open starry sky. The inner shell, which stretches 25% in width, hugs the sleeper perfectly. It offers plenty of space while keeping warmth inside the sleeping bag. The sensitive foot area is excellently insulated by the three-dimensional foot box and provides comfortable freedom for the feet thanks to its ergonomic cut. All models in the Astro Pro series are bluesign products and are made from certified down.
