The Period Company The Sleeper
Summary
The Period Company The Sleeper scores 88/100 — one of the cleanest period-underwear options on the market. Made from 100% certified organic cotton (GOTS-certified) on every layer that contacts skin, including the absorbent core. OEKO-TEX Standard 100 certified for textile chemical safety. Third-party tested for PFAS (forever chemicals) with non-detect results — directly responding to the industry's 2020 PFAS scandal that hit Thinx. The brand is mission-driven (founded by single-mom designer Sasha Markova) with size-inclusive sizing up to 6X and is sold at Target. Bonus: reusable for years, dramatically reducing disposable-product exposure to fragrance and bleached pulp.
