Thinx is machine-washable and reusable period-absorbing underwear — providing a more sustainable alternative to single-use disposable products. Thinx underwear for periods is designed in a range of absorbencies, from lightest to super, to support every stage of your flow. Every pair of Thinx period-absorbing underwear features our signature, innovative built-in technology — a moisture-wicking top layer, an absorbent core layer, and an outermost leak-resistant barrier. Check out our How Thinx Work page to learn more.

Every flow is different! You can wear Thinx underwear for periods for as long as your flow allows. The absorbency style also plays a factor, as some underwear styles are more absorbent than others.

We recommend following the hip measurement to find the most accurate size. Be sure to measure your hips at their widest point, derrière included! We recommend sizing up in underwear styles that fit below the natural waist, or if you're looking for the best fit postpartum. The underwear should fit snugly but not so tight that it becomes uncomfortable.
