Very good swim shorts good quality
Excellent product
although they tend to come up small these are great value and have been perfect for the keen swimmer!
The condition of the pants and the top was terrible after first use in the pool. The strings and fabric started to frail.
I am sorry to hear that you face some problems using the NAVY BLUE 500 BOYS' FIRST NAVY LAY 500 JAMMER SWIMSUIT.
This is the first time this product has a review with the following conditions that you mentioned above. It might be that you picked up a defective product off our shelves.
I would like to invite you personally to any of our store outlets for a FREE exchange or refund for the product. If you require any assistance, you ca find me personally at Joo Koon Decathlon store and I will be able to assist you from there directly.
Hoping to see you soon Vignesh.

My child loves it, i am not sure about durability as he has been using only for 3 weeks
Nice swim but as others have said they are on the small side. I realise they are meant to be close fitting swimmers but for the height/size I would have expected to fit I've had to return and go up from a size 12 to a 14. They were very very snug and would not have lasted very long. But the quality is good which is why I've returned and bought the larger size.
Luck good,nice fit great price
Bought age 8 for my slim 6 year old and they’re tiny. Look good quality though so I will return and try to swap for the age 10
Good quality and perfect fit for the kid. Fully satisfied !
Great fit, good quality and very comfortable!
I have a squad swimmer so his bathers get well, well used. These were a fantastic price, great quality, they look great and he absolutely loves them. Will definately be getting more on my next visit to Decathlon

Additional Product Information
Composition
Main fabric
- 100% Polyester cationic
Main lining
- 100% Polyamide
Style
JAMMER – 13" long (in size 10 years) 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.
Material
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.
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.
Use
Swimwear intended for regular use.
A score to compare the environmental impact of products
The product's environmental impacts are calculated across its entire lifecycle using various 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).

Product testing
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, this product retains its shape.
