Have a shark-free summer with these chic period bathing suits that add stle and leakproof protection.

Heading to the beach on your period is often riddled with instead of being fun, especially if you are worried about leaking or wearing bulky period products. Period bathing suits solve these problems and look incredibly fashionable.

What is a period bathing suit?

Period-proof bathing suits are special swimwear made for that time of the month. They look and feel just like regular swimsuits so there’s no embarrassment, but are made with several layers of absorption material to trap period blood away. These are an alternative to wearing tampons while swimming and are ideal for light and medium-flow days.

Period bathing suits can easily handle between four and eight hours of medium flow, but much like a tampon or pad, will need to be changed after that. When you’re done, they throw right in the washing machine and air-dry till you’re ready to use again.
