Perfect fit
Hello Mohan,
Thank you for your review on our product.

Have a great day :)
Thanks & Regards,
Decathlon Brampton Team
Restarted to swim with a TYR shorts from Amazon, which didn't last two months. So far I'm happy with this purchase, excellent quality product for daily swimmers.
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.

Additional Product Information
Composition
Main fabric
- 100% Polyester cationic
Lining
- 100% Polyamide
Style
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.
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.
