Designed for women seeking enhanced support, this swimsuit top is suitable up to a 105F cup size.
Thanks to its innovative textile underwires adapted for larger busts, the Astrid swimsuit top offers you absolute comfort at the beach and in small waves.
Designed for women seeking enhanced support, this swimsuit top is suitable up to a 105F cup size.
The size or model does not suit you? would you like to make an exchange in your Decathlon store? No problem, just be careful not to cut the swimsuit tag in case you want to exchange it.
Underwires provide support and shape, but they are often rigid and uncomfortable for water sports. The Astrid swimsuit was designed with innovative, more flexible textile underwires that provide good support while naturally shaping the bust.
Women with a cup size larger than D are attentive to support and look for plus-size swimsuits with underwire. We created this Astrid underwired swimsuit top just for you. More than 20 prototypes were needed, along with testing on all body types, to guarantee support and comfort. The straps and bust band are adjustable.
To ensure a perfect fit in the water, we have to adjust our swimsuits while they're still wet, as they stretch out of shape once you're in the water. We therefore advise you to choose the correct size. The swimsuit should fit snugly in the changing room; you should feel supported. The elastane in some of the materials used in our swimsuits softens and stretches in the water.
We work to support women so that they feel good in our swimsuits. The chest is not crushed, the buttocks are not marked, the level of coverage varies. Our mission is to ensure that every woman finds a swimsuit that suits her, whatever her body, her morphology or her size.
Whether you're a surfer or enjoying a swim in the sea, you don't want to lose your swimsuit! That's why we test all of our swimwear in the waves. Each model is designed for surfing and is perfectly suited to other water sports: stand up paddle, windsurfing, kite surfing, swimming, etc.
The size or model does not suit you? would you like to make an exchange in your Decathlon store? No problem, just be careful not to cut the swimsuit tag in case you want to exchange it.
Based in Hendaye, in the southwest of France, OLAIAN is Decathlon's new surf and bodyboard brand. In our offices “feet in the water” we can design a swimsuit in one day, then test it directly at sea to check how well it holds up in the waves.

Underwires provide support and shape, but they are often rigid and uncomfortable for water sports. The Astrid swimsuit was designed with innovative, more flexible textile underwires that provide good support while naturally shaping the bust.
Women with a cup size larger than D are attentive to support and look for plus-size swimsuits with underwire. We created this Astrid underwired swimsuit top just for you. More than 20 prototypes were needed, along with testing on all body types, to guarantee support and comfort. The straps and bust band are adjustable.
To ensure a perfect fit in the water, we have to adjust our swimsuits while they're still wet, as they stretch out of shape once you're in the water. We therefore advise you to choose the correct size. The swimsuit should fit snugly in the changing room; you should feel supported.
