Composition

Built-in 4-layer technology:

- Waterproof membrane — nothing gets out, nothing gets in
- Outer layer — UV50+ protection, chlorine/salt resistant
Durability
On average, a person uses 17,000 disposable products over their menstrual life — that much plastic waste ending up in the oceans.
A single Sybille swimsuit, used for 5 years, replaces around 1,000 tampons. Washable, reusable, no single-use plastic. It's good for you and for the planet.

You put it on in the morning. You didn't think about it again.
