Product Customer Reviews

Recommended
Reasonably good pair of shorts however they have a tendency to ride up the legs.
No way are these large! states they are large size 36?? more like a 30 when stretched .. regarding would I recommend these, hard to say material looks ok maybe a little thin. However these are swim shorts but they are a little thinner than my old swim shorts. But way way to small
Fit well. Fair price what more could anyone ask.
Ordered these swim trunks for my husband in his usual size 32. I shall be returning them as they are ridiculously small. Think they are more like a boys item.
Thank you for your recent feedback. We are sorry to hear that you found our men's swimwear well to small. This model is for regular swimmers which practiced few days a week. These boxers are made with special aqua resist fabric to last longer and the shape is design to give good support and aerodynamic. In dry condition they may create filling of too small but after when you get to into water they should get more flexible. If you are looking for more occasional boxers then I would recommend one of these models: 8331340, 8361310 or 8335897 (the model code to be used in the search bar on Decathlon.co.uk).
Please return your item to local store or use the online procure for full refund or exchange.
Once again apologies for any inconvenience caused.
Kind regards

I bought shorts, running shotts and swimming trunks, all in medium. The shorts and running shorts were a good fit but the swimming trunks were much much smaller
Thank you for your feedback. We are sorry to hear that you find some discrepancies with sizes between Decathlon brands. With the swimwear it is normal that they are much small compare to the standard clothes. The fabric which is usually used to make swimwear expand in the chlorine water and this is why this type of products are really tight. From personal experience as ex professional swimmer I use L or XL board shorts but M or M/L swimwear (boxers or jammers).
If you still feel that the size of boxers is too small for you then please return this item your local store or use the online procedure for full refund or exchange.
Once again apologies for any inconvenience caused.
Kind regards,
KORNEL
Good size and good quality product
The fit was perfect and the style very pleasing .The material is water resistant and perfectly suited for regular long distance swimmers like me.
Банските са удобни, не стягат, не са отпуснати и връзките са достатъчно дълги за да се вържат удобно.
Банските са от много хубава материя на добра цена!
Plavky splňují všechno co mají.

Additional Product Information
Composition
Main fabric
- 100% Polyester cationic
Main lining
- 100% Polyamide
Style
BOXER – length 9.8 in. 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. Boxer swim shorts are ideal for those who prefer a cut that provides more coverage than briefs.
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. - UV resistant: even the brightest of colors will retain their color 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.
Use
Swimwear intended for regular 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 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. For more information, visit: http://sustainability.decathlon.com/
Origin
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.
