Dealing with your period whilst swimming can be tricky, but it doesn’t have to be.
Created with summer in mind, AuntFlo's Period Swimwear allows you to confidently enjoy the beach or pool on your period. Just like our Period Undies, these swimsuits offer our trusted four-layer protection system and a unique water-repellent fabric, ensuring this swimsuit locks periods in, and keeps water out.

Both fun and flirty one piece designs include four-way stretch fabric for a smooth, comfortable fit, medium bum coverage, and built in bust tightness for extra support. Pair your swimwear with a tampon, cup or disk for extra protection if you experience a super heavy flow.
We’re committed to both environmental safety and your comfort. That’s why all AuntFlo Period products are PFAS-free.
This swimsuit provides medium flow coverage and can absorb 10-15ml (equivalent to approximately 2 regular tampons). Use it on its own or as a backup—only you know what works best for your flow.
We’ve got your period covered!
