Fällt klein aus

Schade, die Bikinihose sieht auf der Internetseit gut aus, ist aber durch den Umschlag sehr eng.

Hose viel zu klein

Trotz gleichen Modells wie die Hose in schwarz-lila-pink fällt diese viel zu klein aus. In der gleichen Größe passte die Hose in schwarz-lila-pink.

Fällt sehr klein aus!

Die Hose ist sehr schön und sitzt auch gut, sobald man die passende Größe gefunden hat. Ich musste sie leider in zwei Größen größer bestellen, als ich sonst trage, damit sie passt. Aus diesem Grund gibt es einen Stern Abzug.

Viel zu eng (Größe M)

Normalerweise trage ich Größe M. Die Bikinihose ist leider zu eng geschnitten.

Hallo Sonia,

vielen Dank, dass du dir Zeit genommen hast unsere Bikinihose von Olaian zu bewerten.

wir bedauern natürlich sehr, dass du unzufrieden mit der Größenwahl des Produktes bist. Leider fallen unsere Biknis generell etwas kleiner aus und wir empfehlen eine Nummer größer zu wählen. WIr arbeiten eng mit den Produktmanagern zusammen um die Größenwahl für dich und andere Kunden besser zu gestallten. Du kannst natürlich die Hose im Onlineshop retournieren oder in einer DECATHLON Filiale in deiner Nähe umtauschen.

Wir wünschen dir dennoch einen schönen Tag und entschuldigen uns für die Unannehmlichkeiten.

Mit sportlichen Grüßen
Super Schnitt

Die Bikinihose sieht gut aus und ist bestimmt bequem. Leider hatte ich bei der Bestellung die falsche Größe bestellt .



Leider zu klein wieder !

Habe diese Hose zum passenden oberteil gekauft Leider hat mir die erste Hose gr 38 nicht gepasst. Jetzt hat es diese Hose nur noch in gr 42 gegeben also zwei Nummern größer aber egal falls zu groß kann man's einnähen ... Leider war sie nicht zu groß sondern genau so groß wie die Hose zuvor die 2 Nr kleiner war .. sehr schade mag es nicht wenn die bikinihose so sehr einschneiden...

Hallo Ramona, 

vielen Dank, dass du dir die Zeit genommen hast, deine Erfahrung mit der Bikini-Hose Nao von Olaian zu teilen. Ich bedaure sehr, dass du unzufrieden mit der Passform bist. Tatsächlich fallen die Bikini-Hosen etwas klein aus, weshalb wir empfehlen, ca. 1-2 Nummern größer zu wählen. 

Selbstverständlich hast du die Möglichkeit, dieses Produkt in einer Filiale zurückzugeben, oder an den Onlineshop zu retourniernen. 

Ich hoffe, wir können dich in Zukunft besser von unseren Produkten überzeugen und wünsche dir einen schönen Tag!

Mit sportlichen Grüßen
Schöner Bikini

Schöner Bikini. Der Slip ist jedoch in L für die Größe 38/40 ein Tick zu klein, aber noch tragbar.

You are a regular surfer

You regularly go surfing. During your sessions, you paddle out to the lineup, duck dive under the breaking waves if you are on a shortboard, or turtle roll if you are on a longboard, then surf waves of less than 40". You often fall and are used to being shaken about underwater. Your swimsuit must meet the requirements of your practice and stay in place for each of your movements. We have designed a range for you that is suited to your regular practice and your body shape.

Body shape

For those who prefer not to show any cheek and want to partially cover up their lower abdomen, these classic high waist-shaped briefs are the perfect solution. Reassuring, they nonetheless feature a standard cut leg that will make your legs look great. Their folding waistband lets you adjust the height of the briefs, matching style and coverage to suit a range of body shapes. The elasticated edges ensure the swimsuit stays in place 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.

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.

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:

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.

What is the olaian brand?

Tribord surfing products have now become OLAIAN products, the new Decathlon brand dedicated to surfing, bodyboarding and skimboarding.The markings on all surfing products will gradually be replaced. This is why your product may have a logo different 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, color fastness when rubbed, washed, exposed to sea water, chlorinated water and light, and tests on the product's overall performance after repeated washing.
