The fabric is made up of polyester and spandex creating the 4 way stretch. We then use a nanotechnology from a large US company which is tested to be 100% safe. It's pfoa free after extensive testing.

To try and explain a little bit. We conducted extensive testing on all of our products prior to commercialization to ensure the health and safety of the consumers who will wear our shorts. These technologies have been proven safe in both comprehensive third-party scientific testing as well as in real-world applications as demonstrated by the millions of garments in circulation throughout the world which has been made with this technology.

Our proprietary innovations adhere to the nanotechnology stipulated by the National Nanotechnology Initiative and the Hohenstein International Textile Research Center. WE DO NOT USE NANOPARTICLES IN OUR SHORTS. The technology consist of polymer blends that contain a big molecular main chain and branched chain. The branched chain (nano-sized whiskers) is connected with the main chain (backbone/spine) by a covalent bond, in which the branched chain and main chain are not able to separate by any force. The polymer is relatively large and durably bound to the fabric; so it will not absorb into the skin.
