How does Sorio’s period swimwear absorption work?

Every Sorio Period Bikini Bottom features an innovative four-layer absorption system that allows women and teens to swim safely during their period.

The technology includes:

A soft, honeycombed layer that lets fluid pass through.

An absorbent bamboo-fiber layer that captures and locks in fluid.

A waterproof barrier that prevents leaks and keeps water out.

A UV- and chlorine-resistant outer fabric that ensures long-lasting quality.

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

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?

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.
