Swim Shorts

A bit small to the size chart as mentioned. My son is 8 years old and lean built. But it fits him tightly. May need to change in a couple of months as he grows. Word of advice - buy a size bigger than the chart mentions. It does not have an inner lining fabric, making it thin.It does not have a pocket or a draw string to tighten it. But colour & quality is good. Dries quickly.

Too small

My son is a slim 9 and I ordered the age 10. Very neat and short on him. Yes swimwear should not be baggy but this was just a bit extreme on the neat side.

Excellent product

Value for money

Way too small

My son is a very slim 8 year old and these were far too small - smaller than my five years old’s swimming shorts.

Dear Fiona,Thank you for your recent feedback. We are sorry to hear that you found our boys boxers too small. We are working on new size template for children's clothes to make it more up to today's market. Also we added to each product page, just above the box with size selection blue colour link "find your size" where you can see chart with metric and imperial height linked to each size. In addition to that we made visible customer's feedback where you can check opinion from customers about the size who already bought the product. We are working also on this tool development to make sure in the future everything is in one place and it should help to choose correct size.Please return the item to your local store or use the online procedure for full refund or exchange.Once again apologies for any inconvenience caused.Kind regards  KORNEL

Additional Product Information


Main fabric

  • 100% Polyester cationic


  • 100% Polyamide


BOXER – side height 7.3" (in size 10 years) A swimming swimsuit should primarily favor comfort. It should enable you to move with ease. That is why it is important to choose the shape 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.

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 lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling system. Website: Explanatory video:



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.
