help Thinx FAQ

How many washes can Thinx underwear last through?

Thinx states that their period underwear is designed to last up to two years with proper care, which involves machine washing in cold water and air-drying. Tumble drying or using fabric softeners can degrade the absorbent layers and significantly shorten the lifespan.

Can Thinx completely replace tampons and pads?

For lighter flow days, Thinx can function as a standalone replacement for disposables. On heavier flow days, many users pair Thinx with a menstrual cup or tampon for backup protection, as the absorbency capacity varies by style—super versions hold more than the hiphugger or cheeky cuts.

Do Thinx contain PFAS or harmful chemicals?

Thinx faced a class-action lawsuit regarding the presence of PFAS chemicals in their products, which was settled in 2023. Following the settlement, Thinx stated their products do not intentionally contain PFAS and has pointed to independent testing; however, consumers concerned about chemical exposure may want to review third-party test results.

Which Thinx style holds the most for overnight use?

The Thinx Super line, particularly the Super Hiphugger and Super Sleep Short styles, offers the highest absorbency and is marketed for overnight or heavy-flow use. The Sleep Short specifically provides more coverage for restless sleepers.
