Thinx Underwear Class Action Lawsuit Overview:

  • Who: A Thinx Underwear customer is suing the brand, alleging its underwear is unsafe to wear
  • Why: The plaintiff says Thinx underwear contains harmful chemicals, but market the apparel as safe to wear
  • Where: New York federal court

Thinx underwear contains harmful chemicals which are a safety hazard to the human body and the environment, but it markets the underwear as safe to wear, a new class action lawsuit alleges.

Plaintiff Nicole Dickens filed the class action lawsuit against Thinx Inc. May 25 in a New York federal court alleging violations of state and federal consumer laws. 

Dickens says she purchased two pairs of the Thinx Underwear from Thinx’s website in May 2016. 

Because of the company’s marketing of the underwear as a menstrual product alternative, she says she believed that the underwear would serve as a safe, healthy, environmentally-friendly and chemical-free alternative to traditional menstrual products.

However, in November 2020, Dickens became aware of reports that Thinx underwear contained harmful chemicals, and stopped using the product. Her lawsuit alleges that the brand deceived women into paying for a dangerous product at a price premium. 

“Through its uniform, widespread, nationwide advertising campaign, Defendant has led consumers to believe that Thinx Underwear is a safe, healthy and sustainable choice for women, and that it is free of harmful chemicals,” she says.

“In reality, Thinx Underwear contains harmful chemicals, including multiple polyfluoroalkyl substances (PFAS) and silver nanoparticles, which are a safety hazard to the female body and the environment.” 

Customer Seeks Damages for Herself and Others

Dickens says her own independent testing has confirmed the existence of “harmful chemicals” in Thinx’s products using industry standard testing. 

She says the presence of the chemicals contradicts Thinx’s unvarying representations that the product is nontoxic, environmentally friendly, and otherwise safe for women and the environment.

If customers knew the underwear contained harmful chemicals, such as PFAS, they would not have purchased the underwear or they would have paid less for it, Dickens says.

She is suing on behalf of anyone in Florida who bought Thinx Underwear. Dickens is seeking certification of the class action lawsuit, damages, fees, costs, interest and a jury trial. 

Thinx was hit with a similar class action lawsuit in 2021, alleging that despite marketing proclaiming that Thinx are nontoxic, harmless, organic, and safe, the underwear contains several harmful chemicals that pose a “safety hazard to the female body.”
