I’m a thong that can absorb period blood and I could do a triathlon. I’ve got the nice discreet feeling of a thong and the serious backup of being highly absorbent. Please play the Eye of The Tiger the first time you put me on. You’ll see. The Sporty Thong is made from PeriodTech™ fabric - a super stretchy Nylon and Spandex knit that moves with you. As always, the gusset is made with organic cotton by Period Co. When To Wear: For moments when you need a sporty thong, You will know those moments. The Period. Company is PFAS free and proud of it. Here’s how they make that possible: Before going into production, each Period. fabric is tested by Intertek Labs to ensure the fabric passes both CA PROP 65 And a PFAS panel. The CA prop 65 panel tests for over 400 toxins and carcinogens, in addition to a wide range of PFAS. Then, during production, Period. consumer tests the bulk product at UL labs. These tests include color fastness, shrinkage, performance and another round of heavy metal and PFAS testing. Each piece of Period. fabric has to pass these tests otherwise they don’t make it out of the door. Period. have been tested by numerous consumer groups and have just received a validation from UL of ‘PFAS NOT DETECTED’ for all products.
