We are happy to make socks for you from organic cotton or bamboo viscose. The material composition would be

Organic cotton: 80% organic cotton, 17% polyamide, 3% elastane
Bamboo viscose: 80% bamboo viscose, 17% polyamide, 3% elastane

With organic cotton just as many colors are possible as with normal cotton, with bamboo viscose unfortunately only very few colors are possible. So if bamboo viscose is desired, we have to clarify in advance whether your design can be realized in the desired colors.
