Period Bikini Bottoms

Don't let your period ruin your beach day. Our period-proof bikini bottoms combine the style of your favorite swimwear with discreet leak-proof technology. Choose your perfect fit, mix and match tops, and dive in with confidence.

Discreet Leak-Proof Technology Built In

Modibodi's period bikini bottoms have a lot going on beneath the surface. A hidden absorbent liner locks away your flow, while a water-repellent layer prevents pool and ocean water from soaking in. And it's all so lightweight and seamless, no one will know you're wearing period swimwear.

Just like our popular period underwear, choose your absorbency based on your flow and how long you'll be wearing them. Light absorbency is great for spotting and light bladder leaks, but our Moderate absorbency can handle up to 30ml – that's the equivalent of 6 tampons! If you're unsure, check out our absorbency guide for more information.

Stylish Bikini Bottoms for Your Period

We've perfected the technology, but it's just as important that you feel amazing wearing them. That's why we've incorporated our leak-proof magic into styles you'll love. High-waisted, cheeky Brazilian, boyleg shorts, stunning one-pieces – we've got you covered.

Pair your perfect bottoms with any of our tops for a bikini combination that's all your own. Play with coverage, switch up your straps, and find that perfect fit with the help of our size guide. Congratulations, you've found your ideal swimwear.

A period bikini has leak-proof protection built right into the swim bottoms. The liner draws in period blood or light bladder leaks, while the water-resistant layer helps keep the outside water out so the bottoms stay nice and discreet while you get in and out of the water.

Yes, Modibodi period bikini bottoms are designed to be worn without a tampon or pad. Pick an absorbency level suited to your flow, and check or change your bottoms as needed, just as you would with any other period product.

Rinse your period bikini swimmers in cold, fresh water straight after wear. Then, use a gentle cold machine wash and hang them to dry in a shady spot. Skip soaking, bleach, fabric softeners, tumble dryers and the iron as it may affect the protective liner.
