One Piece n°2 - Mediterranean Blue

$118.00 USD

2 in stock

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

The cut

- 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 can be fastened in 3 ways with an Italian knot system: straight, crossed in the back or behind the neck.
- No iron or plastic (let's avoid micro-waste) to adjust the straps but knots. The knots are small and pleasant to wear. As far as adjustment is concerned, the iron eyelets slide very poorly on swimsuit 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 can paddle and swim comfortably!

Size advice
To choose your size of one piece, refer to your stocking size. For example, if you are a size 36 in panties, take a size S in one piece. The straps are adjustable and will fit your top.
This swimsuit fits normally. If you are over 1m70 and not sure which size to choose, go up a size.

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.

J’ai bien reçu les 2 maillots commandés, ils sont parfaits ! De très bonne qualité et ils me mettent vraiment en valeur ! Merci encore pour vos beaux produits !

Parfait !

Une coupe élégante, une couleur intemporelle, des finitions impeccables, un joli décolleté avant-arrière, tout en donnant l'impression d'être habillée pour la plage. Le tissu est souple, doux, soyeux, agréable. C'est un indispensable qui vient renouveler la garde-robe d'été. La taille convient et met joliment en valeur la silhouette.
