We’ve rigorously tested every size for fit *and* function with actual people on their periods, so you can trust Thinx as your go-to protection. 💪
Because our period underwear hugs your body, there’s nowhere for leaks to go! Every pair moves with you, keeping you covered.
Our underwear can completely replace single-use disposables — a sustainable switch that’s better for you & better for the planet.
Thinx are constructed to absorb flow, control odor, prevent leaks, and hug your body — so your period goes in and nothing comes out. With a better fit, you’ll have better protection. ☂️
