Fabrics wear out too quickly

I am disappointed with the quality of the fabric for the price. The fabric is already very threadbare behind, it is transparent, so you can see my behind through! I can no longer wear it.

You are an expert surfer

You surf intensively, it is your favorite sport. During your sessions, you paddle out to the lineup, duck dive under the breaking waves if you are on a shortboard, or turtle roll if you are on a longboard. You show commitment in powerful waves of more than 40”. Your swimsuit must stay in place for each of your movements, whatever the strength of the wave. We have designed a range for you that is suited to your intensive practice and your body shape.

Body shape

Especially suited to surfing and bodyboarding, the Isa 1-piece is the ideal swimsuit for surfers looking to combine comfort and femininity; all of the seams have been designed to protect the stomach from friction against the board and the wax, and to leave the shoulders and shoulder blades free to paddle. Its neckline and bodycon effect make it particularly feminine.

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 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 spandex 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 Southwest 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 make sure it stays in place in the waves.

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 strength, colorfastness when rubbed, washed, exposed to sea water, chlorinated water and light, and tests on the product's overall performance after repeated washing.
