Product Customer Reviews

Great fit, I definitely recommend!!!
This costume fits great, looks great for your local gym but also nice enough to wear surfing in the sea or at the local spa due to its nice V front Normally get about 9months use out of this at the gym using it 1-2 times a week with hand wash before the chlorine starts getting to it which is pretty good tbh
I am a UK Size 14/16 and have struggled to find a flattering swimming costume until now. I can only say that this costume is amazing. It looks good, and all my friends thought it came from a much more expensive top of the range UK women’s sports brand. If you are between sizes get a size up. I decided that with the costume looking as good as it does I don’t care that it’s the 16 that fitted me best.
very pretty but a bit too dark and serious when on
Sexy 1 piece seimsuit. Fitting all shapes of body. Good quality & beautiful design. Also perfect for hard swimmers!

You are an expert surfer
You surf intensively, it is your favorite sport. 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. You show commitment in powerful waves of more than 40". Your swimsuit must stay in place for each of your movements, whatever the strength of the wave. We have designed a range for you that is suited to your intensive practice and your body shape.
Body shape
Especially suited to surfing and bodyboarding, the Isa 1-piece is the ideal swimsuit for surfers looking to combine comfort and femininity; all of the seams have been designed to protect the stomach from friction against the board and the wax, and to leave the shoulders and shoulder blades free to paddle. Its neckline and bodycon effect make it particularly feminine.
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 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.
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.
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: http://sustainability.decathlon.com/
