Thinx for All™ reflects our goal of giving more people access to better periods! To offer this period-absorbing underwear at a more accessible price point, we value-engineered a simple design with a single-lined cotton fabric body in a limited selection of styles, colors, and absorbencies.
Thinx for All is a curated collection of single-lined cotton underwear for periods in our most popular colors & absorbencies, to make period underwear more accessible for all. Thinx is our line of period underwear & apparel, available in exclusive silhouettes and premium fabrics like luxe mesh and Modal Cotton.
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 period-absorbing underwear for as long as your flow will allow. And of course, the style you wear also plays a factor, as some underwear styles are more absorbent than others. We measure our underwear for periods by absorbency, with our highest absorbency styles holding up to 5 tampons worth of flow. For some customers, they will last the whole day, and others may need to carry an extra pair of Thinx period underwear as a backup. If you feel damp or notice your flow spreading to the seams, that is an indicator you should change into a fresh pair. We suggest bringing along a resealable bag, pouch, or wet bag — so that if you do need to change out of your first pair of Thinx undies, you've got a place to put them. If you're unsure which styles to start with, we recommend taking our Know Your Flow quiz.
We recommend following the hip measurement to find the most accurate size. Be sure to measure your hips at their widest point, derriere included! We recommend sizing up in underwear styles that fit below the natural waist. Check the fit details of each underwear style via our size chart. The underwear should fit snugly but not so tight that it becomes uncomfortable.
