There are two main types of diaper fabrics: absorbent fabric and waterproof fabric. This category is for absorbant fabrics made primarily from bamboo viscose. Our bamboo fabrics are made from processed bamboo fiber blended with organic cotton. All of our bamboo fabrics are made from Oeko-Tex Standard 100 certified bamboo fiber - the strictest standard for infant apparel worn next to the skin - tested and found to be free of all known harmful substances.
