You are a 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 suitable for discovering the waves and to suit the body shape of young surfer girls for a secure fit in tiny waves.

Body shape

We designed this Bali 2-piece swimsuit so that all young surfer girls can have fun and discover the waves. The bikini top with spaghetti straps stays in place in the waves. The swimsuit is easy to pack away into its built-in pocket, so that the young surfer can take it with her anywhere.

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 if possible.

Our girls' swimsuit sizes

Here is the link between age and height on our swimsuit labels: 4/5 years: from 3 ft5 Inch to 3 ft9 Inch5 years: from 3 ft9 Inch to 4 ft1 Inch7/8 years: from 4 ft1 Inch to 4 ft4 Inch8/9 years: from 4 ft4 Inch to 4 ft8 Inch10/11 years: from 4 ft8 Inch to 4 ft11 Inch12/13 years: from 4 ft11 Inch to 5 ft3 Inch14/15 years: from 5 ft3 Inch to 5 ft7 Inch

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.

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.

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 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 field-tested in Hendaye and has been subjected to numerous laboratory tests to guarantee the quality of use for which it was designed: tests on the elasticity and stability of the fabric, colorfastness during rubbing, washing, exposure to sea water, chlorinated water, and light, and overall performance of the product after several washes.
