Explore LUNA swimwearIt's a question almost every woman asks when she first hears about period swimwear.
Period swimwear isn't regular underwear with a pad. It's designed specifically for being in the water.
An absorbent section inside the swimwear helps hold small amounts of fluid.
The layers help keep blood inside. But the swimwear can't stop every leak, and its capacity is limited.
On lighter days, you can wear it on its own, depending on your flow. On heavier days, pair it with a menstrual cup or tampon.
