The advantages of our winter underwear

Conventional functional underwear is often unable to neutralise perspiration odours and at the same time wick sweat away from the skin. Hy-performance® is a climate-active textile technology that minimises the growth of bacteria and at the same time optimally releases perspiration to the outer layers of clothing as it forms. Inorganic active ingredients are incorporated directly into the textiles, so their function is retained even after repeated washing. hy-performance® unfolds its full effect through body heat. hy-performance® prevents the proliferation of microorganisms and keeps you dry thanks to integrated sweat management.

The popular sheep's wool

Until the 19th century, wool was a precious material and was only worn by privileged and wealthy citizens. Since Europe has been able to import sheep's wool from Australia and New Zealand, it has been available in large quantities and has thus become affordable for the general population. The shorn coat of sheep is also called fleece and consists of (1) the outer layer of hair, which is stiff and coarse and protects against the weather, and (2) the inner layer of hair, which is soft and fine and regulates body temperature. As a rule, sheep's wool is obtained from the inner hair. The fluffy feel is created by the scaly outer layer of the hair and its crimp, which varies greatly depending on the breed. The more uniform the fibre structure, the better the quality of the clothing. In Germany, sheep are usually shorn once a year. On average, each sheep produces 3.5kg of wool, the value of which varies according to breed and age. Due to breeding, the amount has tripled.
