In Australia and Marocco, sheep are exposed to blistering heat without breaking a sweat. Their close relatives that graze wetlands in Northern Germany don’t mind the damp climate. Why? Sheep wool insulates!
The natural curl of the wool fiber traps air pockets in the fleece, which acts as a buffer for heat as well as cold. Gently processed wool retains this ability which is why woven and knitted wool fabrics show the same characteristics. No wonder the Bedouin Tribes choose wool to make their tents (Burnus) from; they want to stay cool!
The first Himalayan expedition teams who were wearing wool garments felt the same insulation benefits. The insulation ability of wool kept them comfortable in even the most extreme climates and allowed them to perform under the most adverse conditions.
Furthermore: the wool fiber is extremely elastic. The fiber can be stretched up to 30 % beyond its original length and bounces back to its original shape even when crushed – a naturally wrinkle resistant fiber!
But wait, there is more: Wool performs excellently when exposed to moisture. Large water drops run off the surface thanks to a membrane around the outer layer of the fiber. At the same time, wool can absorb up to 33% of its own weight in moisture (steam) before feeling wet, which makes it an excellent active wear fiber.
All these exceptional qualities are naturally preserved and even enhanced in our GEIGER Walk_Fabric.
