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

How long can I wear one pair?

It depends on flow and style. As a guide: a style with 20–30 ml lasts six to eight hours on a medium day; one with 40–50 ml can last a full night.

Do they show under tight clothing?

The seamless high-waist brief leaves no lines. Ribbed and lace styles can be slightly visible under very thin fabrics.

How do I wash them?

Rinse cold, machine wash cold on a gentle cycle, no fabric softener or bleach, air-dry.

How long do they last?

Around two years with care per the instructions.
