Tee-Owels are made of absorbent, organic cotton blend t-shirt material. Our fabric contains 95% organic cotton and 5% spandex for durability and slight stretchiness. We've found this fabric combination to be particularly ideal for hair drying because the texture of the cotton is very soft and absorbent, while the 5% spandex contributes to the smooth surface, and makes our towels uniquely more durable and longer lasting than other hair towels. Not to mention, Tee-Owels are super form-fitting and more fun and easy to style for this reason! All of our material is responsibly sourced.
