These are true to size, and comfy to wear. However, having only been worn and washed three times, the material is already ‘bobbling’

Great for swimming in
Excellent product, well worth the money. Just as good as products twice the price
This is the third time that I have to go and send back jammers at Decathlon. I have no idea how you do your sizing but definitely the swimwear and most clothes are way to small. I have bought swimming jammers for my 13 year old son who is a normal 13yo. The 14-15 children's doesn't fit him, so I got this men's swimming jammer, size M as the size S look smaller that the kids one. Well, the jammers are very tight specially in the legs. They are not size M at all! They won't fit a grown up man. This problem in sizing goes across most of your products. I was a big fan of Decathlon but not anymore. Waste of time!
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
簡單大方,好穿。
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.

Swimming jammer style
SWIMMING JAMMER – 44 cm longThe JAMMER is ideal for anyone who wants to surpass themselves. A 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.
Material
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.
Aquaresist technology
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 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, trousers, backpacks).Decathlon is a committed stakeholder in this environmental labelling approach.Web: Sustainability.decathlon.comVideo: https://youtu.be/8t63KkRwn_8
