This new yarn from Classic Elite is made of what it sounds like: 100% bamboo, a natural fiber from renewable resources. An eco-friendly yarn with many of the same qualities as rayon. It has excellent drape, plus a wicking quality that will keep you cool and dry in the summer. That natural quality inherent in the fiber is what makes it great for your sheets and high performance socks and the like. Also, bamboo fiber is naturally antibacterial, making it a great yarn for baby and children's items.
