As expected. Hard to judge chlorine resistance as I haven't had them long.

Unbeatable value for the price!!

Having previously made my first purchase from Decathlon online, this time I was lucky to go in and try them on. Buying a size up seems to be the safest bet.

Credit where credit is due!

This is a splendid product - fits well, feels comfortable and lasts well. The advice about how to remove water after swimming seems important. I used 'wringing' with the first ones I got and the elastane did seem to suffer. Now I follow the advice to squeeze out the water and that seem to prevent damage. Also take a measuring tape when buying: the size is somewhat variable depending in part on where they have been made. But I am a real supporter - it's a great choice!

Ordered but not received

Ordered this item twice, received a email saying all is well, then email saying that they cannot get them and a full refund will be received still waiting for my refund

Blue Perfect

Finally got this great pair of briefs after many goes that Decathlon messed up my order delivery no matter how many times I tried to contact them. Anyway goods received that fits perfectly for swimming in the pool as well as the Open Water. It also enhances my assets whilst walking the pool side or the beach. The blue colour is also great but can't wait to see a red brief in a similar design because I'd it straight away. This brief is perfect for us breaststroke swimmers as described and much use in the pool.

Good briefs

Nice to swim in, they feel good and are affordable. They fit quite well especially at the back. Could use a bit more room up front as they are a little tight and revealing.

Fantastic basic trunks

Simple, value for money, basic swimming trunks. Look good, fit well and (so far) wearing well. Ideal for training.

Great swimming basic

Looking for basic quality swimming trunks, you've found them. C'mon Decathlon bring back the black ones (and even add navy or get the blue ones back in stock).

Perfect for the pool or beach

Normally we say "you get what you pay for". With these swim briefs you get a lot more than what you pay for. They fit well and are true to size. The quality is excellent. I have since bought the grey version.

Additional Product Information


Main fabric

  • 82% Polyamide
  • 18% Spandex


  • 100% Polyester cationic


SWIMMING TRUNKS – side height 2.75 in. First and foremost, a swimsuit should be comfortable. It should enable you to move with ease. That is why it is important to choose the shape of your swimwear carefully. The cut of swimming briefs is classic and timeless, providing a good hold and plenty of freedom of movement.


Very comfortable and soft with excellent stretch properties. Chlorinated water can be harmful to swimsuits that are used repeatedly in swimming pools. The spandex fiber that gives the material its stretch and therefore makes it comfortable, also becomes fragile when in contact with chlorine. If you swim occasionally, this material will be fine for you; otherwise, opt for a 100% polyester material.

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire lifecycle 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, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling system. For more information, visit:



Storage instructions

store in a dry place.

Care instructions

Rinse with clean water and leave out to dry after each use. Not recommended for use on slides to ensure that your swimsuit lasts as long as possible.
