When the brand Thought found out from their sock factory that there was lots of leftover yarn from previous orders they needed to think of a way to use it up! This led their buying and design team to create these new favourite Thought classics — the Rainbow 7 pack of socks. They have made them in every size from baby to mens and womens! They are made in Thought's signature bamboo and organic cotton blend yarn. The box is reusable and was exclusively designed by the in-house graphic designer. All of the gift boxes are made using FSC card and vegan glue. These sustainable socks are breathable and naturally anti-bacterial, so your feet (and the planet) stay happy and healthy. 64% VISCOSE DERIVED FROM BAMBOO 26% ORGANIC COTTON* 8% RECYCLED POLYESTER** 2% ELASTANE   *certified organic cotton. **Certified Global Recycled Standard
