Technical information

Your practice

Swimming for beginners: beginner swimmers who are starting to swim and looking for 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 range of swimwear that allows her to swim with products suited to swimming, but that also meet anatomical requirements.


U-shaped back: A swimsuit should primarily favour comfort. It should allow you to perform your movements with ease and not hurt you. That is why it is important to choose the shape of the back of your swimsuit carefully.


Chlorinated water can be harmful to swimsuits which are used repeatedly in the swimming pool. The elastane fibre that gives the material its stretch property and therefore makes it comfortable, is also very fragile when in contact with chlorine. If you swim occasionally this material will be fine for you. If you swim regularly or intensively, opt for a 100% polyester material.

Bra cups
