Nice
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
JAMMERS – length 17.3'' First and foremost, a swimsuit should be comfortable. It should enable you to move with ease. That's why it is important to choose the cut of your swimwear carefully. The jammers provide great muscle compression for the quads and glutes, resulting in the perfect fit.
Material
100% polyester Our engineers have developed a polyester-based textile and replaced the spandex fibers with PBT fibers. These give it sufficient elasticity to ensure user comfort while protecting it against the damaging effects of chlorine. This PBT thread - is quick-drying. - only loses 3 to 4% resistance throughout its lifespan. - UV-resistant: even the brightest colors will retain their colorfastness.
Aquaresist technology
Products bearing the AQUARESIST label are guaranteed to deliver resistance to chlorine 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 intensive use.
Score to compare the environmental impact of products
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.

Imported
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.
Storage instructions
Store the swim shorts in a dry place.
