underwear that absorbs your period

Thinx are washable, reusable underwear designed to replace pads and tampons, or be worn with tampons and cups for extra protection.

Basically, they look and feel just like your regular undies — but better.

how Thinx does its thing

Every pair of Thinx is made with our signature, innovative technology for the ultimate period protection.

how Thinx works for *you*

Every person and every period is unique, which is why it’s good to ~know your flow~. See how Thinx works for these one-of-a-kind people with periods.

caring for Thinx

Thinx are *very* simple to care for — throw ‘em in with the rest of your laundry (your other clothes will be fine!), then hang them up to dry. No need to iron, or use bleach or fabric softener.

switch to Thinx

Changing up a comfortable routine can be a challenge, which is why we recommend trying Thinx at home first, so you can get familiar with how they work for your flow.

Thinx can serve as a complete replacement to traditional period products (like pads and liners), and you can also wear Thinx as a back-up to tampons and cups.

Try starting with our best-selling Hiphugger, which absorbs up to 2 regular tampons’ worth of flow.

Find a pair (or 2 or 3!) that go with *your* flow.
