OUR TECHNOLOGY - OUR SIGNATURE
A breathable honeycomb layer that lets flow through, an absorbent fabric that captures and channels it, a waterproof layer that blocks leaks, and an anti-chlorine, UV-protective outer fabric.
Our waterproof layer is reinforced, and that makes all the difference in the water.
It prevents anything from seeping out. In the ocean or the pool, the protection holds, with no unpleasant surprises.
No extra bulk, no visible layer. From the outside, it looks like regular swimwear and no one can tell it's period swimwear.

IN THE PRESS
YOUR QUESTIONS
Does period swimwear really work in the water?
Yes. Our swimwear is specially designed for use in the water. Its absorption capacity is equivalent to 3 tampons. Extra protection may be needed for a very heavy flow.
Is there a risk the swimwear will absorb water?
No. The third, waterproof layer acts as a barrier between blood and the water outside: the flow stays in the absorbent layer and the protection doesn't absorb water. There's no risk of the crotch ballooning in the water.
What's the difference between medium flow and heavy flow?
It's measured by the number of period products you need. Medium flow is equivalent to up to 3 tampons, heavy flow 3 to 4 tampons.
Is the swimwear suitable for teens?
Absolutely. Our teen range is designed for first periods, with sizes starting at 3XS, for ages 10 and up.
