Es algo más recortado por detrás de lo que me pareció al probármelo en la tienda, pero aún así es cómodo y de un tejido robusto.

You are an intermediate 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.

Active at the beach!

Whether you be a surfer or enjoy bathing in the sea, you don’t want to lose your swimsuit! This is why we test all our swimsuits in the waves. Each model is designed for surfing and perfectly suits other water sports: stand-up paddle boarding, sailing, kite surfing, bathing, etc.

Body shape

The ALY briefs were created for women who want classic briefs, with medium but feminine coverage. Our stylist therefore imagined very thin side edges to indent the thigh and visually lengthen the leg.

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.

Comfortable in our swimwear

We strive to support women to ensure they feel comfortable in our swimwear. The chest is not squashed, the buttocks are not emphasised, coverage levels vary. Our mission is to ensure that every woman finds a swimming costume that suits her, whatever her body type or size.

Removal of plastic hygiene stickers from our swimwear

From 2022, all women's swimsuits designed by Decathlon will be sold without plastic hygiene stickers. This responsible decision was made to help protect our planet and reduce plastic use. Saving 940 km of plastic every year!Please do your bit by always keeping your underwear on in our changing rooms.

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.

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 stretch and stability, colour-fastness when rubbed, washed, exposed to sea water, chlorinated water and light, and tests on the product's overall performance after several washes.
