Additional Product Information

  • 18% Spandex

Main lining

  • 100% Polyester cationic


Your daughter is a beginner surfer, practicing in very small waves. She stays in sight, where she can still touch the bottom. She wants to play in the waves and discover new sensations. While learning to surf, she’ll only wipe out in weak waves. These swimsuits are specifically tailored to young surfers so that they stay in place in the waves.

Body shape

The TINA swimsuit was designed so that young surfers could play freely in the foam. The fixed triangles are perfectly adapted to the body shape of young girls who have not yet begun to develop. The adjustable neck helps keep the suit in place in small waves.

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 child'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 height, weight and shape 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 years: from 3'3" to 3'5" 5 years: from 3'5" to 3'9" 6 years: from 3'9" to 4'1" 8 years: from 4'1" to 4'3" 10 years: from 4'4" to 4'8" 12 years: from 4'8" to 4'11" 14 years: from 4'11" to 5'3" 16 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, you should feel supported. The spandex contained 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 will 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 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 check it stays in place in the waves

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 chose to apply this voluntary environmental labeling system. 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 elasticity and strength, colorfastness when rubbed, washed, exposed to sea water, chlorinated water and light, and tests on the product's overall performance after several washes.
