Hi. Bamboo fabric is completely environmentally friendly. Thanks to modern technology, socks are made from natural materials such as bamboo fibers. This method of production has gained popularity quite recently, but is very fond of all over the world thanks to eco-friendly clean production technologies. Today bamboo fiber occupies the leading position among the materials for the production of socks. I bought socks made from bamboo for my family as they are very comfortbale and soft.
