Rethink your cycle with Thinx — period-proof underwear that absorbs menstrual flow, fights leaks and odors, and keeps you fresh and dry. Depending on your flow, Thinx period-proof underwear can replace or be worn as back-up leak protection for tampons, pads, liners, and cups.

Our soft, cozy, and breathable Organic Cotton collection is made from (you guessed it!) 100% organic cotton. The Organic Cotton Brief style absorbs up to 2 regular tampons’ worth of your flow — with a fit and feel that’s as comfortable as your favorite pair of sweats. Our natural fiber is GOTS-certified, which means it’s ethically and sustainably sourced — a switch that’s better for your period *and* the planet.

At Thinx, we’re on a mission to empower every body through innovative solutions and social change. When you purchase our underwear, you’re supporting our initiatives at our GiveRise program, where we — alongside our partners — are fighting for better access to puberty education, amplifying grassroots activism, and donating our undies and time.

The Thinx Organic Cotton Brief absorbs up to 2 tampons’ worth of your flow, and is recommended for moderate days on your period. Our underwear can be worn as a replacement or back-up leak protection for other period products, including tampons, pads, liners, and cups.

Thinx period-proof underwear can work a little differently for everyone, so we recommend trying them at home first to get a sense for how they’ll work for you.

How to use

• • Rinse your underwear in cold water immediately after use.
  • Put them in a mesh laundry bag, and machine wash with your laundry on a delicate cycle. Please avoid fabric softener and bleach, as these products can hurt our period-proof technology.
  • Hang your underwear up to dry, and wear again.
