Our Menstrual Bikini Bottoms for Women and Teens

Periods Shouldn’t Stop You from Enjoying the Water

Your period should never keep you from a beach day or a swim in the pool.
That’s why we created our collection of menstrual bikini bottoms, designed for women and teens who want comfort, protection, and style with total freedom to swim anytime.

How Do Menstrual Bikini Bottoms Work?

Our period-proof bikini bottoms feature four ultra-thin technical layers that discreetly channel and absorb your flow:

  1. A hypoallergenic layer that stays soft and gentle on your skin.

  2. A micro-perforated barrier that lets blood pass through and nothing else.

  3. An absorbent core that locks in menstrual flow and prevents leaks.

  4. A waterproof outer layer resistant to water, chlorine, and UV rays.

The result?
Four super-thin layers that keep you protected, invisible, and confident even in the water.

So you can swim, tan, or move freely without worrying about your period.

Are Menstrual Bikini Bottoms Really Effective?

Absolutely.
Our swimsuits are lab-tested and real-life approved to offer reliable, discreet protection, whether you’re swimming, lounging, or walking along the beach.

Is period swimwear effective enough protection for swimming when you have your period?

Obviously, they are designed to offer women the possibility of swimming during their period, without the need for tampons! Reliable absorbent technology is integrated into the swimsuit, allowing it to absorb menstrual flow, retain it and prevent water from entering. Zero leakage guaranteed, no need for additional protection. Our period swimwear is designed for light to moderate flow, absorbing the equivalent of 2 to 3 tampons. The flow level is specified on each of our product information sheets.

Are period swimwear visible underwater?

Our period swimwear features a reliable yet thin and discreet absorbent layer. It looks just like regular swimwear and does not swell up in water. Enjoy peace of mind and a healthy, tampon-free, hassle-free period solution.
Are period swimwear easy to care for? How long do they last?

Caring for your period swimwear is relatively simple: after each use, rinse the swimwear in cold water, then machine wash it at 30°C. Avoid using fabric softener and tumble drying to preserve the absorbent technology. Our period swimwear has an average lifespan of 5 years, but this may vary depending on how you use and care for your period swimwear.
