BOXER SHORTS – length 25 cm A swimming swimsuit should primarily favour comfort. It should enable you to move with ease. That is why it is important to choose the shape of your swimwear carefully.
Our engineers have developed a Polyester-based textile and replaced the elastane fibres with PBT fibres that give it sufficient elasticity to ensure user comfort whilst protecting it against the damaging effects of chlorine. The benefits of this PBT thread are - quick drying. - only loses 3 to 4% resistance throughout its lifespan. - Even the brightest of colours will retain their colour-fastness.
Products bearing the AQUARESIST label are guaranteed to deliver chlorine resistance throughout their lifespan. They will maintain their elasticity and are UV resistant. For these reasons they are recommended for regular or intensive pool use.
Score to compare the environmental impact of products
The environmental impact of the product is calculated over its entire life cycle 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, trousers, backpacks, etc.). Decathlon chose to apply this voluntary environmental labelling scheme. For more information, visit:

    First purchase from Decathlon

    The training are comfortable and so far I'm very pleased with them. The swimming trunks are a bit on the small side.

    What's going on with your sizing?

    Far too small, even though similar sized running tights fit perfectly. Had to return, I'm afraid. Might even just wear the running tights.

    Comfortable, good fit

    After a few weeks this is the best swimsuit I’ve ever lapped in. Even fit & pressure, not over-tight thigh hems don’t seem to ride up or down.

    Note for Canadian buyers - watch the sizing, I’m usually a medium from most outlets, but couldn’t even pull them on. Wearing L, and they’re certainly not loose.
