Thinx for All
Everyday period underwear made from comfy cotton, available in our most popular absorbency levels.
Even on my heaviest day, they still did not soak through. The soft material was comfortable and I was pleasantly surprised at how absorbent they are.

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 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.
