Sizing is very good, you'll find one that fits well without pinching. Otherwise, just your basic jammers. I liked the first pair so much, I went to buy a second one. I'm satisfied, but colors are boring. Colors helps your family to recognize you at practice or competition. Only black and blue, black and orange. boring.
I found these after seeing someone wearing jamners on holiday that came from Decathlon. Unfortunately they were discontinued but these are equally as stylish, comfortable and dow the job. Great value for money. I'd still fancy some of the others too.
Have other jammers from Decathlon on the strength of the quality and fit I bought these and have no regrets (Edith Piaf starts to sing) I’ve got pair of Speedo’s and they don’t come anywhere near these bad boys. I will be buying more in the future and only from Decathlon for certain.
Bought these as swimming regularly and needed some extra shorts whilst the others dried. Far superior quality to the more expensive speedo jammers I bought recently and seem to add to buoyancy when I swim distance. I will definitely buy again.
Bought these as I noticed a lot of the top swimmers wearing them and as I used to compete myself and didn’t want to offend the world with me in a pair of budgie smugglers t tried and love these trunks. I’ve ordered some more as the quality of them leave my speedo’s For dead in comparison a very good buy indeed
Good for my 10 y old boy
Excellent swim wear for my use - 3 swims a week about 3k each swim.
Reasonable quality and long lasting.
I bought these as I'm learning front crawl, and I must say that they seem so much better that loose "leisure shorts". It feels like I've ditched a parachute now. Sizing was as expected and the length is good. Comfort is good with no rubbing or pressure points.
Make sure they are a tight fit as they jammers always loosen up slightly when wet.

JAMMER – 17.3" long The JAMMER is ideal for anyone who wants to surpass themselves. A swimsuit should primarily favor comfort. It should enable you to move with ease. That's why it is important to choose the cut of your swimwear carefully.
Our engineers have developed a Polyester-based textile and replaced the spandex fibers with PBT fibers that give it sufficient elasticity to ensure user comfort while 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 colors will retain their colorfastness.
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.
The environmental impact of the product is calculated over its entire lifecycle and with different indicators. An overall ABCDE rating is performed to help you easily identify the products with the best environmental performance by comparing the same type of products with each other (T-shirts, pants, backpacks). Decathlon is a committed stakeholder in this environmental labeling approach. Web: Sustainability.decathlon.com Video: https://youtu.be/8t63KkRwn_8
The environmental impact of the product is calculated with different indicators over its entire lifecycle. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance. Use the score to compare products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this environmental labeling system.

The products labeled with AQUARESIST certification are tested under repeated cyclical loading in a pool of chlorinated water for 240 hours. No deterioration of elastic strength was observed throughout the test. Unlike a standard swimming product, the product remains intact.
