Multi Hi-Waist Set

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 our line of comfy cotton period underwear in a streamlined selection of styles and colors. Each pair is designed with our built-in leakproof lining that absorbs your flow for up to 12 hours while staying discreetly thin and dry.

Thinx is our premium line of period underwear that comes in a wider variety of styles, fabrics, and absorbencies to work with your flow.

Our underwear for periods absorbs your flow, blocks out odor, wicks moisture, and prevents leaks — so you feel fresh, dry, and comfortable! No pads, tampons, or other period products are needed. Our period-absorbing underwear is washable and reusable — providing a more sustainable alternative to single-use disposable products.

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.
