period-proof underwear that works

if we all had periods, maybe we’d be more comfortable with them.

Nearly half of the world’s population has a period, yet we still shy away from having open conversations about them. So we thought to ourselves — what would the world look like if everyone had them?

Hey, we’re Thinx. Since 2013, we’ve been helping people around the world period better — with underwear that absorbs your flow.

ready for a change?

Meaningful innovation hasn’t happened in the menstrual hygiene space in nearly 80 years. What gives? We knew that it was about time for a change, and that’s why we created Thinx — period-proof underwear that works.

how it works

Our underwear has built-in technology that absorbs your flow, wicks moisture, controls odors, and prevents leaks — keeping you fresh and dry, all cycle long. With up to 4 tampons’ worth of absorbency, Thinx can completely replace what you’re using today.
