Made from naturally-renewable resources, these bamboo and cotton socks are not only environmentally friendly, but also feel luxuriously soft next to your skin. The viscose material that's derived from bamboo is moisture absorbing and thermo-regulating to help keep your skin warm in the winter and cool during the summer. Socks made from bamboo have particular natural anti-bacterial functions, bacteriostasis and deodorization value. Its test results show over 70% of bacteria perished when incubated on bamboo fibre. In addition, tests by the Japanese Textile Inspection Association found that, even after 50 times of washing, bamboo fabric still possessed these functions. Bamboo allows socks to help keep feet fresher for longer and healthier as the fabric naturally stops bacteria from spreading.
