SHOP ALL RUNTERRAsustainability
Runterra is made from premium, long-staple Supima® cotton which is 50% longer and up to 45% stronger than other cottons (and softer too). The stronger the fiber, the more durable the garment, and therefore the more it can be worn. Supima® cotton is grown by a select few family farms that utilize advanced water and soil management techniques to reduce consumption and ensure the health of the land for optimal renewability.
Runterra fabric is also OEKO-TEX® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.
