If you bought a pair of Thinx Period Underwear, you may be eligible for reimbursement thanks to a class-action lawsuit that was announced in November 2022.

The lawsuit alleges that Thinx, a New York-based company that launched in 2013, used potentially harmful chemicals called PFAS in the underwear without telling customers.

Although Thinx has denied any wrongdoing and emphasized the settlement was not a submission of guilt, the company agreed to pay up to $5 million to settle claims that its period underwear contained PFAS. Thinx agreed to pay $4 million for claims submitted by customers and provide up to an additional $1 million if needed to cover any valid claims.

The U.S. District Court for the Southern District of New York gave the settlement its preliminary approval in December, more than two years after the litigation began. The case combines two existing lawsuits filed in California and Massachusetts.

Why was this lawsuit filed?

The Thinx class lawsuit makes allegations regarding the presence of short-chain per-and polyfluoroalkyl substances, Agion anti-microbial treatment, and the organic cotton line of the underwear.

According to studies, PFAS are referred to as “forever chemicals” because of their ability to permanently linger in the water, soil, and air. Exposure to PFAS has been associated with thyroid cancer, high cholesterol, low birth weight and an increased risk of some cancers, including liver cancer.

Who’s eligible for reimbursement?

Anyone who purchased a pair of Thinx Period Underwear between November 12, 2016, and November, 28, 2022, may be eligible for compensation. According to the lawsuit, Thnk Period Underwear refers to Cotton Brief, Cotton Bikini, Cotton Thong, Sport, Hiphugger, Hi-Waist, Boyshort, French Cut, Cheeky, and Thong.

How much compensation can you receive?
