Fällt schmal aus

Meine Tochter liebt das Muster, aber leider fällt er eher schmal aus. Sie hat eine normale Figur bei 114 cm, dieser Bikini ist aber leider bereits zu eng. Daher habe ich ihn eine Nr. größer nochmal bestellt.

Sehr schönes Design, Oberteil enger als Unterteil

Ich habe den Bikini in Gr. 110 für meine 5-jährige Tochter bestellt, die normalerweise Gr. 104 trägt. Sie hat noch ein kleines Babybäuchlein. Dennoch oasst das Höschen gut und das Oberteil ist ihr etwas zu eng. Da sie das Oberteil aber nur für den Schwimmkurs braucht (und nicht am Strand) haben wir den Bikini behalten :)

grösser bestellen!

Qualität sehr gut, sitzt gut, fällt aber sehr klein aus, mindestens 1 Größe kleiner

Beginning surfers

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

This BONI 2-piece swimsuit has been designed for young surfers just waiting to discover the joys of the sport. She wants to be out on the waves in the summer but wants her swimsuit to stay in place. With the shape of the top and crossed back straps, your little surfer can practice without worrying about her swimsuit. The X-shaped cross back allows for optimal 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 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.

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 in store if possible

Our girls' swimwear 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.

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 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.
