All raw materials are thoroughly tested and carefully selected. All materials meet the Öko-Tex 100 standard, and there are no harmful additives or processing agents used. Thus the products are suitable even for the most sensitive skin. The use of elastane fibres such as Lycra® make the socks extra flexible. Coolmax® and polypropylene’s moisture transfer ability makes them ideal for technical sport socks. The successively knitted fibre layers give technical socks a multilayer structure that keeps the feet warm or cool as needed.
