Grüezi-Bag Biopod Wool Zero XL Sleeping Bag night blue

The Biopod Wolle Zero is the ideal all-round sleeping bag for trekking, camping and biking, even when it gets wetter. The pillow compartment is also very practical - just put a fleece jacket in here, for example, and you have a pillow that doesn't slip while you sleep.

The mummy sleeping bag has an innovative zipper that allows you to comfortably put your feet on the top of the sleeping bag when it gets too warm. A deep and restful sleep is especially important after an active day. That's why Grüezi bag sleeping bags have a more comfortable cut, while paying attention to light weight and small packing volume. Thanks to the patented wool layer construction, sleeping bags with AlmWolle insulation offer an incomparable feel-good climate for a restful sleep, even with increased humidity.

Advantages of the unique Almwolle Insulation
The lavalan AlmWolle used in the Grüezi bag products creates an excellent microclimate: the body releases moisture at all times. However, if there is too much humidity, the body begins to freeze. Wool absorbs moisture and passes it on to the outside in doses so that there is no evaporation cold. This regulation enables a warming or cooling effect to enable a dry, comfortable climate. In addition, wool keeps you warm even when it is damp.

Tip
When the sleeping bag is unpacked for the first time, it needs some time to become fluffy. If you iron the sleeping bag loosely with a steam iron and on a silk setting before using it for the first time, the wool rises faster and it can then regulate the climate better.
