Technical information

Your practice

Beginner swimming: the beginner swimmer is new to swimming and needs comfort and coverage. She seeks above all a physical activity linked to water, for its benefits on her well-being and on her health. For her, Nabaiji offers a wide choice of swimsuits that allow her to swim with suitable products, but which also meet her morphological needs.


"U" back
A swimming swimsuit should focus on comfort above all. It should allow you to perform your movements with ease and not hurt you. For this, great importance must be given to the choice of the back of your swimsuit.

To be preferred for large sizes as it is easier to put on when passing through the hips.


Main fabric: 82% - Polyester 18% - Elastane. Our engineers developed a polyester-based fabric and replaced the elastane fibre with PBT fibre, which is stretchy enough to provide user comfort but, more importantly, is unaffected by chlorine. This PBT thread also has the advantage of quick drying. It only loses 3 to 4% resistance throughout its lifespan. Another plus: even the brightest of colours will retain their colour fastness

Bra cups

This swimsuit has integrated padded cups.

Restrictions of use

Not recommended for use on slides. For use in public swimming pools, please check that this type of swimsuit is permitted by the establishment

Why doesn’t my swimsuit have a hygienic sticker?

As of 2022, all women’s swimwear designed at Decathlon are made without plastic stickers. If all the stickers were in a line, that would make 940km of plastic saved every year!
This meaningful decision is strongly based on protecting our planet and limiting the use of plastics.
Let’s make this responsibility a common commitment by making sure to keep one’s underwear on when one goes in the fitting room.
