I love this set. They're so comfy, easy to wash, and look great. It’s so nice to have enough pairs to last my whole cycle. I haven’t used disposable products in years!

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.
Our absorbent styles hold from 1 regular tampon worth of flow to 5 regular tampons worth, so there is a style right for each day of your cycle. We recommend trying Thinx period-absorbing underwear for the first time at home to see how each underwear style works with your ~flow~.
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.
Our sustainable period underwear is super easy to care for. Machine wash the undies with the rest of your laundry on a cold cycle before first wear and after each use. Steer clear of fabric softener and bleach. Hang dry to keep your undies at maximum performance. Do not iron.
We typically process return orders within 1–2 business days. Once processed, US exchange orders are shipped via standard shipping and should arrive within 5–7 business days. International exchange orders are shipped via UPS Worldwide Expedited DDP.
