No, our underwear does not contain PFAS. Our underwear materials are certified Standard 100 by OEKO-TEX (TM), an international association that ensures a high level of safety from harmful substances in textile products. There are many different types of PFAS (Per- and polyfluoroalkyl substances).
OEKO-TEX tests for the most common PFAS in textiles as part of their certification process. In addition, Cora tests each lot of Period Underwear in the USA with a 3rd party lab to ensure compliance.
