Women's 1-Piece Swimsuit - Isa Black

Resistant to impact of waves

Carefully designed to stay in place in waves of more than one metre.

You are an advanced surfer

Being an advanced surfer means you surf often and intensively. During your sessions, you paddle out to the lineup and feel comfortable duck diving or turtle rolling under waves. You show no fear in waves of more than one metre. Your swimsuit has to stay in place, whatever the strength of the wave. This line was designed for intense surfing sessions, for all body types.

Versatile beachwear

Whether you’re surfing or swimming, you don’t want to lose your swimsuit! This is why we test all our swimsuits in the waves. This model is designed for surfing, but is also suitable for sports such as stand-up paddle boarding, sailing, and swimming.

Body type

Especially suited to surfing and bodyboarding, the Isa one-piece is the ideal swimsuit for surfers looking to combine comfort and femininity; the seams were 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

Our swimsuits are designed to stay in place in the waves. Our women’s styles are tested by a panel of female surfers with different body types. They’re first tested in a pool under simulated surfing conditions, then worn during real sessions in the ocean.

Dry sizing and wet sizing

Swimsuits become looser when wet, so it’s important to choose the correct size. Your swimsuit should fit snugly when you try it on in the fitting room. Keep in mind that the elastane in some of our swimsuits softens and relaxes in the water.

Comfortable swimwear

Every woman deserves to feel comfortable and confident in her swimwear. That’s why our swimsuits are designed for all body types, with styles that provide varying degrees of coverage.

Removal of plastic hygiene stickers from our swimwear

As of 2022, all women’s Decathlon-designed swimsuits will be sold without plastic hygiene stickers. This decision was made to help protect our planet and reduce plastic waste. It’ll save 940 km of plastic every year! Please do your part by keeping your underwear on in our changing rooms.

Are you unhappy with the size or style? Would you like to exchange it at your Decathlon store? No problem, just be sure not to cut off the tag in case you want to exchange it.
