All products are crafted with care in the USA from recycled cotton. The yarns are created by recovering the scraps from the production of other cotton products, mainly t-shirts. All of the little cotton scraps are gathered together and ground up so that they can be re-spun into "new" yarn. The yarns are then knit into colorful socks. These recycled yarns are certified to be free from harmful substances (i.e. toxins like formaldehyde), made with respect for the environment and with respect for human rights.
