What is your return policy?

We offer free returns and exchanges within 60 days of purchase, no questions asked! Just visit the Thinx Inc. Return & Exchange Center to get started.

How do Thinx work?

Thinx are underwear that absorb your period. Every pair is made with a patented design and our signature technology that absorbs your flow, wicks moisture, controls odor, and prevents leaks — leaving you fresh and dry. Take a look at our How it Works page to learn more.

How long can I wear Thinx?

We measure our undies by absorbency with our highest absorbency styles holding 4 tampons worth of fluid. For some customers, that means wearing them the whole day and for others that may mean carrying an extra pair of Thinx as a backup. If you have more questions, please try our Know Your Flow quiz.

How do I know what size to buy?

We recommend following the hip measurement, as most of our styles sit on the hips. Be sure to measure your hips at their widest point (derriere included!) to find the most accurate size for you! In case you don't have a tape measure, you can use the size you usually are most comfortable with for your underwear. We recommend the undies fit snuggly, but not so tight that it's uncomfortable. For reference, you can check out our Thinx size chart.
