Buena prenda

En mi caso, me va bien porque no me puede dar mucho el sol. El problema que encuentro es que el top que lleva dentro no aguanta lo suficiente. Pero, es una prenda que va bien. No lo recomiendo en spa, se hincha

maillot de bain

topissime. couvre bien la poitrine et sans descend bien bas au niveau du ventre. super qualité.


Très bien pour celles qui ne veulent pas être trop dénudée sur le sable tout en profitant du soleil. Le ventre est caché avec ce modèle. Dommage qu’il n’y ait pas plus de choix dans ce type de produit. Prix accessible. Utilisé en borde mer: résiste parfaitement

Bonjour Madame,
je vous remercie d'avoir pris le temps de nous adresser votre avis concernant le tankini IONA. Je comprends tout à fait votre déception et vous invite à procéder à un échange dans votre Decathlon le plus proche soit en optant pour notre autre tankini, le modèle INES : soit le modèle de votre choix. Je vous conseille cependant d'effectuer un passage en cabine pour vous assurer que cela corresponde bien à votre morphologie. Merci encore de votre confiance.

bonne tenue


haut de maillot bain avec brassière intégrée très joli, pratique. Sert même de débardeur. Je l'avais déjà acheté en rose/corail. Dommage qu'il n'y ai pas de couleur flashy ...

You are an experienced surfer

You regularly go surfing. During your sessions, you paddle out to the line up, duck dive under the breaking waves if you are on a shortboard, or turtle roll if you are on a longboard, then surf waves of less than one metre. You often fall and are used to being shaken about underwater. Your swimsuit must meet the requirements of your practice and stay in place for each of your movements. We have designed a range for you that is suited to your regular practice and your body shape.

Body shape

For women who want to combine the freedom of a two-piece with the comfort and coverage of a one-piece, a tankini is the ideal swimsuit top! Unlike one-piece swimsuits, which impose the same size for the bust and the hips, you can choose your tankini top and briefs separately. With its unique shape inspired by a tank top, the IONA tankini top can be worn as a bikini top or a third piece for a bikini and is therefore suitable for pregnant women.

Stays in place in the waves: the test

We design swimsuits that promise to stay in place in the waves. To test them, we use a panel of at least 12 female surfers with different body shapes who will follow a test protocol in a pool at our design offices in Hendaye. This protocol aims to reproduce the sensations experienced by surfers when being thrown around by a wave. If this test is conclusive, we go surfing in the sea to test our swimwear in real conditions

Dry sizing and wet sizing

To ensure a perfect fit in the water, it is important to choose the right size while you are dry because once they are in the water, swimsuits become looser. We therefore recommend you buy the correct size. The swimsuit needs to fit snugly against your body in the fitting room, you should feel supported. The elastane contained in certain components used in the design of our swimsuits softens and relaxes in the water.

Do you want to exchange your swimsuit?

Is the size or style not suitable for you? Would you like to exchange it at your Decathlon store? No problem, just be sure not to cut off the label of the swimsuit in case you want to exchange it.

Olaian, decathlon's surf brand

Based in Hendaye, in South West France, OLAIAN is Decathlon's new surfing and bodyboarding brand. In our offices at the water's edge, we can design a swimsuit and then on the same day test it directly in the sea to check it stays in place in the waves

What is olaian?

Tribord surfing products have now become OLAIAN products, the new Decathlon brand dedicated to surfing, bodyboarding and skimboarding. Gradually, the branding of all our surfing products will be replaced. Therefore, your product may display a different logo to that shown in the image of the product.



Product testing

This product has been tested in use in Hendaye and has been subjected to numerous laboratory tests to guarantee the quality of use for which it was designed: tests on the fabric's elasticity and stability, colour fastness when rubbed, washed, exposed to sea water, chlorinated water and light, and tests on the product's overall performance after repeated washing.

Superior quality. Unbeatable prices.

For 40 years, Decathlon has delivered the best value in the retail sports industry by offering high-quality, sustainable and cost-effective products.
