Additional Product Information


Main fabric: 100.0% Polyethylene Terephtalate

Body shape

These boardshorts are designed for young girl surfers wanting to have fun and discover waves. With their belted waistband, the boardshorts stay in place in the waves and easily adapt to fit all body shapes.

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. Two 10-year-old girls can be of totally different heights, weights and shapes, and have different measurements. We also recommend trying the swimsuits on if possible.

Our girls' swimsuit sizes

Here is the link between age and height on our swimsuit labels:8/9 years: from 133 to 142 cm10/11 years: from 143 to 150 cm12/13 years: from 151 to 160 cm14/15 years: from 161 to 169 cm

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 elastane content in certain components used in the design of our swimsuits softens and relaxes in the water.

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. 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

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.

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 to 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, colour-fastness when subject to friction, washing, sea water, chlorinated water and exposure to light, and the product's overall performance after several washes.
