7 Best Period Bathing Suits 2024

A day at the pool or beach is a blast — except if you or your teen is on the verge of getting their period. It can be an anxiety-inducing experience rather than a fun one, especially if you are worried about leaking or bulky period products. Thankfully, period bathing suits solve these problems.

What is a period bathing suit?

Period-proof bathing suits are special swimsuits made just for women on their periods. They look just like regular swimsuits but are designed to absorb period blood as an alternative to wearing tampons while swimming. Wear on light flow days for the same amount of time you'd wear a tampon—somewhere between an hour and six to eight hours.

What to look for in period bathing suits

Style, comfort and function all come together in period bathing suits. These clever designs have absorbent inserts to wick away period blood while keeping you secure.
