Super cute and functional

Love it! Maybe the best swim top I ordered from Decathlon. Fit is true to size and nice cut. Flattering. Wish I had two!

Best bra I’ve found yet!

Absolutely love the adjustable fit of this bra top. As a relatively small chested woman who often finds herself between sizes with cups too large and band sizes too tight, this crop top bra fits perfectly, offering comfort and support in all the right places and looks great. Delighted, and going to buy another!

Plavky jsou pohodlné a hezky sedí. Jen bylo těžké vybrat, protože všechny plavky na prodejně byly více či méně poškozené od ramínek.

Velikost sedí, objem hrudníku 100cm, pod 80cm. Krásně drží prsa tam, kde mají být.

PERFEKT (nochmal bestellt ;)

Ich habe mit 75C keine kleine Oberweite, sondern Brüste, die schon etwas Halt brauchen, den gibt dieses Oberteil - und mit der besonderen Schnürung bzw. der kleinen Aussparung vorne hat es auch einen stylishen Look. ((nur schade, dass es keine schöne/passende Hose - ohne fetten "Olian"-Aufdruck gibt))

Schönes Teil

Schönes Teil, gut gemacht, aber leider nicht für kleine Oberweiten (habe 75A und habe 75 B bestellt, da das das kleinste verfügbare war. Umfang hat gut gepasst, vorne zu groß. Sonst denke ich dass das Oberteil sehr angenehm zu tragen ist.

You are an intermediate surfer

You regularly go surfing. 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, then surf waves of less than 40”. 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

When a surfer makes it up to the peak and gets wiped out by a wave, she doesn't have time to fix her swimsuit. That’s why we designed the Agatha crop top for advanced surfers. The light rounded neckline and wide elastic under the bust ensure a secure fit. An opening between the breasts allows water to flow out. Double adjustable back (top of back and under the bust) keeps the swimsuit in place in the waves.

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.
