How it works
Three layers, one job.
The construction is the same in underwear and swimwear. Only the outer fabric differs — in swimwear it is also water-repellent and carries UPF 50+ sun protection.
1
Inner layer
The smooth layer against your skin moves moisture straight through, so nothing feels wet.
2
Absorbent core
Breathable PUL or TPU takes up the fluid, locks it in and prevents odour.
3
Outer layer
The waterproof layer holds everything back. In swimwear it also repels pool and sea water.

Frequently asked
Can I swim in chlorine and salt water?
Yes. The fabrics are made for pool and sea water. Rinse in cold water afterwards so chlorine and salt do not attack the fibres.
Is anything visible in the water?
No. The absorbent core is sewn into the lining and invisible from the outside. The outer layer is water-repellent, so nothing escapes when you leave the water.
How long can I wear it?
Depending on your flow; the bikini bottom holds 10–20 ml, the swimsuit and skirt 20–30 ml. For a full beach day, bring a second piece to change into.
Do they have UV protection?
The bikini bottom and swim skirt carry UPF 50+ sun protection in the main fabric.
