The material composition of the socks is primarily related to the design. Certain patterns and designs, for example, require more polyamide in production than others. The majority of patterns are made with around 70% organic cotton (GOTS), 28% recycled polyamide and 2% elastane. With this composition, the socks receive the GOTS certificate. If the proportion of organic cotton falls below 70%, our socks are certified with the Oeko-Tex Standard 100. All of our socks have the Oeko-Tex Standard 100. This means we can guarantee that our socks are absolutely harmless to health because they are free from harmful substances.
