How does Leakproof Swimwear work?

The layers work to trap and absorb your period so it doesn’t leak in the water (or on land). Similar Leakproof Technology to our Period Underwear, but with an additional thin layer of waterproof material for extra protection. So blood stays in and water stays out.

✔Discrete
Looks just like a regular swimsuit.


✔Absorbent
Absorbs about 3 tsp of blood.


✔Machine washable
Easily wash and lay flat to dry.
