A chameleon with wool for natural air conditioning. For comfort campers: warm blanket and sleeping bag in one! Thanks to its rectangular form, this lightweight sleeping bag can also used as a blanket. Its high-quality 2-layer filling does not only provide very good insulation, the wool in it also functions like a natural air-conditioning system.
Due to its breathable wool filling, the Biopod Wool Goas Sleeping Bag from Grüezi-Bag can store an enormous amount of air and provides humidity control: it has a cooling effect when it is warm and a warming effect when temperatures are cooler. Another layer of synth down transfers humidity to the wool, so that there always is a dry feeling inside the sleeping bag.
The highly breathable outer material of the Biopod Wool Goas is water-repellent, dries very fast and does not rustle. On the inside, there is highly breathable micro fibre which is soft and agreeable to the skin. A retaining strap prevents any pinching when opening or closing the zipper. In addition, the zipper can be opened at the bottom, which improves air circulation. Useful detail: the zipper tag is a compass! Pillow pocket: just put a fleece jacket in and you have a pillow which does not shift.
How Almwolle 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.
