period-proof underwear that works

You asked, we listened: period-proof organic cotton undies are here!

THINX can be worn as a back-up or replacement to traditional period products. Depending on your flow (light, medium, heavy), THINX can replace pads and liners or be worn with tampons and cups for extra protection.
