The ideal sleeping bag for huts and travelling. The Biopod Wolle alpine hut blanket sleeping bag from Grüezi bag is the ideal sleeping bag for the hut and when travelling. Thanks to its rectangular shape, you can also simply use the sleeping bag as a blanket. You can insert a pillow into the practical and hygienic pillow envelope on the underside if required. In line with its intended use, the sleeping bag has a slightly more comfortable cut, but still weighs in at just 550 g (without pack sack). The pack volume of 13 x 20 cm when compressed is also extremely manageable. Wool insulation, customisation possible. The special feature of the sleeping bag is the insulation, as the temperature-regulating properties of the sheep's wool always ensure a balanced climate. If you want to extend the range of use of the Biopod Wolle Almhütte, Grüezi bag also offers a sleeping bag warmer, which significantly increases the versatility of this sleeping bag.
