I thought the Niki was a swimsuit - but it was only the bottom. This was not clear when I ordered. Thanks Colette
Příjemný materiál, velikost odpovídá, dobrá cena.
skvěle padnou, příjemný materiál
Toller Stoff und sitzt super
Passform und Tragekomfort sind gut. Das Material erscheint mir sobjektiv nicht so super angenehm und "kuschelig" wie wie bei anderen Decathlonprodukten. Das Pres Leistungsverhältnis ist trotzden sehr gut.
Leider bisschen zu klein aber sonst mega gut
Guter Sitz, passt genau
Rundum zufrieden! Super Qualität zu fairem Preis
Der Bikini-Slip zeichnet sich durch seine gute Verarbeitung, seinen guten Sitz und dank des dekorativen Musters durch seine gute Kobinierbarkeit aus.
sitzt perfekt, toller Schnitt
Sitzt gut und behält auch beim Baden ihre Form. fällt allerdings etwas klein aus.

You are an intermediate 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 activity and stay in place for each of your movements. We have designed a range for you that is suited to regular activity and your body shape.
Body shape
For those who do not want to have their rear on display, these classic bikini bottoms offer perfect coverage. Reassuring, they feature a standard-cut leg that will make your legs look great. The low rise of these bikini bottoms is better suited to smaller women, but also to women who accept their body shape and prefer 2-piece swimsuits. The elastic edges ensure the swimsuit stays in place in the waves.
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.
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 content 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.
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, colorfastness when subject to friction, washing, sea water, chlorinated water, and exposure to light, and the product's overall performance after several washes.
