Minimal bottom coverage

Bought a size 10 for my slim 14 year old daughter - she usually takes a size 8 in clothing but having read the reviews we sized up. The top half fit well and looked beautiful but not enough fabric in the bottom/pants area and so it didn't adequately cover her bottom and it made her feel uncomfortable so we have sent it back. The back of the pants has a very low cut scoop so this design is probably not ideal for taller people! Otherwise the quality looked good and we have ordered another Oliana swimsuit instead - delivery and returns always hassle-free with Decathlon.

Sexy one

Krásně sedí mojí postavě, nikde nepřekáží pohybu ani se nezařezávají, zavázání je jednak zajímavé esteticky a druhak je velmi pohodlné a nějak podvědomě mě nutí mít narovnáná záda, což velmi oceňuji, no a za tu cenu jsou zkrátka božské

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 activity and stay in place for each of your movements. We have designed a range for you that is suited to regular activity and your body shape.

Body shape

Especially suited to surfing and bodyboarding, the Andrea 1-piece swimsuit is one of our best for staying in place in the waves. In addition, it provides great coverage at the front to protect the surfer's stomach from irritation from the board and the wax, while at the same time having a very open back to leave the shoulders and shoulder blades free to paddle. The back tie is adjustable and can be worn in an H or X shape depending on the surfer's preference and body shape. With removable cups.

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 follow a test protocol in a pool at our design offices in Hendaye, southwest France. The protocol is designed 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.

What are padded cups?

Shaped cups built in to the swimsuit top are flattering for your bust and sculpt your breasts into a rounded shape without having visible seams and avoiding irritation as opposed to cut and stitched foam pads. Olaian has kept you and your comfort in mind by favoring the use of padded cups in most of its models. The padded cups may be removable and, if so, they let you go up or down a half size.

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, and you should feel supported. The spandex content 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.

A score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon has voluntarily opted to apply this environmental labeling scheme. For more information, visit:



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.
