Thanks to its Alpine wool filling, it offers an excellent climate and very good insulation values due to the second layer of Synthdown. Alpine Wool provides warmth and absorbs moisture. This creates an excellent sleeping climate. The sleeping climate is decisive for sleep quality. The deeper and more relaxed your sleep, the more rested you will be the next morning.
The Zero XL is lightweight and has a small pack size. Thanks to the extraordinary position of the two-way zipper on the Biopod Wool Zero XL, you can place your feet on the outside of the sleeping bag in warm nights, which is very hygienic. If you put, e. g., a fleece jacket into the pillow pocket, the Zero XL provides a pillow which does not shift. Ideal conditions for restful sleep.
How Almwolle by lavalan works
Our body requires a lot of energy to regulate its temperature. Sheep’s wool offsets the climate and therefore partly takes care of temperature regulation. The remaining energy can be used to help the body recover. The processed Almwolle used in Biopod sleeping bags acts as a natural air conditioning system: the body is constantly emitting moisture. However, when it gets too humid in the sleeping bag, the body gets very cold and it is no longer possible to sleep well. Wool absorbs the moisture and releases it outwards. It does so in small amounts to prevent evaporative cooling. This regulates the temperature in the sleeping bag, retaining heat or cooling, to create comfortable conditions for a restful sleep. Wool also provides warmth in damp conditions. Grüezi bag uses wool from sheep in the Alps as the filling for its product line, Biopod. Durable, natural, bio-degradable and renewable: Sheep’s wool, in this case special Almwolle, can be shorn annually.
