Used to using under wire bikini this was just as good and much more comfortable without underwire
Leider zu klein
Sitzt, hält, passt. Gewohnte BH-Größe passt perfekt. Sehr angenehm fürs Schwimmtrainig
Trage normalerweise 70D, passt sehr gut, hält super, sehr schöner Schnitt und Farben.
Top, sitzt perfekt, nichts verrutscht und hab damit ein mega sicheres Gefühl bei allen Bewegungen, ohne Angst zu haben es springt gleich was oben raus (das hatte ich bisher bei noch keinem Bikinioberteil). Sehr gute Qualität! Ich glaub ich leg mir ein zweites auf Lager
Paßt, sitzt, hat Luft
Sitzt gut, passt gut!
Excelente

Da un buen soporte y no te tienes que preocupar de que se mueva. bonito diseño. La talla corresponde.
Muy cómodo
Muy cómodo. Sujeción excelente. Estampado muy ponible para diferentes usos. Súper recomendable para cualquier actividad relacionada con agua.
Cómodo y completo. Sujeción al 100%
No se mueve. Pero es bastante grande si vas a tomar el sol. Da una talla muy pequeña.
Cuesta mucho de poner y de quitar. Un broche por detrás o por delante facilitaría el proceso. Por lo demás, todo bien
Es muy bonito ,queda genial y no se mueve sin duda me comprare otro en distinto color.

You are an advanced surfer
You surf intensively, and it is your favorite sport. During your sessions, you paddle out to the lineup and duck-dive under the breaking waves if you are on a shortboard or turtle-roll if you are on a longboard. You show dedication 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 surfing and 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 paddleboarding, sailing, kite surfing, bathing, etc.
Body shape
Those who enjoy surfing in waves of over 40” know how essential the proper holding of their swimsuit is! That's why we designed the Isa bikini top. Its wide elastic under the bust gives it very good stability whatever the power of the wave or the maneuvers performed. Its open back is adjustable to best fit the morphology of the surfer; The shoulders are free, paddling is easier.
Stays in place in the waves: the test
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, and you should feel supported. The spandex content in certain materials used in the design of our swimsuits softens and relaxes in the water.
Feel beautiful in our swimsuits
For 6 years, we have been working to show women's bodies with one goal: to make women feel beautiful in our swimwear. The chest is not crushed, the rear is not highlighted, and the cleavage is enhanced. Our mission is to ensure that every woman, whatever her body type or size, finds a swimsuit that suits her.
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 stretch and stability, colorfastness when subject to friction, washing, sea water, chlorinated water, and exposure to light, and the product's overall performance after several washes.
