Our sophisticated eco-friendly one-piece. It has a strip of fabric that enhances the neckline and turns into straps.

The cup

  • Adapt the top to your desires, your morphology, your chest and choose your level of support thanks to removable foams slipped under an extra soft lining
  • Adjustable straps that attach in 3 ways using a system of Italian knots: straight, crossed in the back or behind the neck.
  • No iron or plastic (avoid micro waste) to adjust the straps but knots. The bows are small in size and comfortable to wear. On the adjustment side, the iron eyelets slide very badly on jersey materials and tend to loosen the straps too quickly; on the contrary, the knots do not loosen when you are in motion.

All our models have been tested by excellent swimmers and water sports enthusiasts, in the south of France or during their trips abroad. With this one you are comfortable for paddle and swim quietly!

Size advice
To choose your one-piece size, refer to your bottom size. For example if you take 36 in panties, take S in one piece. The straps are wide adjustable and will adapt to your top.
This jersey fits normally. If you measure more than 1m70 and you hesitate between two sizes, take the size above.

In case of doubts or questions about the size, do not hesitate to write to us at

Fabric & Care

Posidonia's objective is to use a fabric that contributes to cleaning the oceans and the environment, but also very elegant and comfortable to free women from any constraint of movement. An eco-responsible jersey is also a sustainable jersey, which is why I have chosen the highest range of European fabric made up of waste such as fishing nets and plastic bottles.

The sea and the salt do not alter your swimsuits if you rinse them with fresh water after each use. Let it dry flat or laid out on its own.

Hand wash your swimsuit. You can wash it in the washing machine at the end of your vacation, on a delicate cycle (max. 30 degrees), with a non-detergent detergent, without spinning or drying cycle.

The chlorine resistance index of our materials is very good. The colors, however, are more delicate.

Produit qui semble être de bonne qualité avec de belles finitions et très agréable à porter. Le tout en ayant la satisfaction de porter un vêtement écoresponsable. J’ai bien aimé le sac pour ramasser les déchets sur la plage!
