It comes off easily

This bikini has two parts and my daughter has worn only the bottom part most of the time. When putting the two together I have seen how it looks like two different bikinis and the colors of the part that has been used the most have changed. It has been very ugly, in only 6 or 7 uses, I do not recommend it at all.

Beginner surfer

For a girl who is starting to surf in very small waves. She stays where she can touch the bottom and is supervised. She wants to have fun in the waves and enjoy new experiences. While learning to surf, she will wipe out in waves that are not at all powerful. We have designed swimwear to suit the body shape of young surfers for a secure fit in the waves.

Body shape

The Boni 2-piece swimsuit has been designed for the budding surfer girl who wants to discover the fun of this sport. She likes to surf in a swimsuit in the summer but wants her swimsuit to stay in place in the waves. With its crop top shape and cross back, the young surfer can surf without worrying about her swimsuit. The X-shaped cross back gives ideal freedom of movement.

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 at least 12 female surfers with different body shapes who follow a test protocol in a pool at our design offices in Hendaye. 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.

Girls' swimsuit sizes

At Decathlon, we design swimsuits for young surfers by taking into account their growth. It is for this reason that we systematically associate the kid's height with the size, as age is not sufficient to guarantee the correct size. 2 10-year-old girls can be of totally different heights, weights, and shapes and have different measurements. We also recommend trying the swimsuits on in store if possible

Our girls' swimwear sizes:

Here is the link between age and height on our swimsuit labels: 4/5 years: from 3'5” to 3'9”5/6 years: from 3'9” to 4'1”7/8 years: from 4'1” to 4'4”8/9 years: from 4'4” to 4'8”10/11 years: from 4'8” to 4'11”12/13 years: from 4'11” to 5'3”14/15 years: from 5'3” to 5'7”

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 materials 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.

What is the olaian brand?

Tribord surfing products have now become Olaian products, the new Decathlon brand dedicated to surfing, bodyboarding, and skimboarding. Gradually, the branding of all our surfing products will be replaced. This is why your product may have a different logo from the one in the picture illustrating the product.

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.
