start period-ing better

Wear THINX as a replacement or back-up to traditional period products.
Depending on your flow (light, medium, heavy), our period-proof undies can replace pads and tampons, or be worn with tampons and cups for extra protection.
Like regular underwear, but so much better. ✨🙌

our signature leak-fighting tech

Every pair of THINX is made with our signature 4-layer technology for ultimate period protection.

but, wait — how do I use them?

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 menstruators.

rinse & reuse

THINX are washable, reusable, and simple to care for. After rinsing, wash them separately, or with the rest of your laundry (just steer clear of bleach and fabric softener!).

get started

Try THINX at home first, where you’re most comfortable, to test how it works for your flow. We recommend starting with our best-selling Hiphugger, which holds up to 2 regular tampons’ worth.
If you have a light flow, you may be able to wear THINX instead of traditional period products, like pads and liners. If you have a heavy flow you may choose to wear THINX as a back-up to your tampon or cup.
