Technical Information

SWIMMING TRUNKS – side height 7 cm A swimming swimsuit should primarily favour comfort. It should enable you to move with ease. That is why it is important to choose the shape of your swimwear carefully. The cut of swimming briefs or trunks is classic and timeless, providing great support and plenty of freedom of movement.
100% polyester Our engineers have developed a Polyester based textile and replaced the elastane fibres with PBT fibres that give it sufficient elasticity to ensure user comfort whilst 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 colours will retain their colour-fastness.
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.
Swimwear intended for regular use.
Score to compare the environmental impact of products

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, trousers, backpacks, etc.). Decathlon chose to apply this voluntary environmental labelling scheme. For more information, visit:

900 Plus Men's Swim Briefs - Black
Used for 2 to 8 weeks
This is my second pair of these swim briefs. They are used weekly in the pool under my Decathlon shorty while I teach a SCUBA class. The original pair have survived very well, so I bought this second pair to extend their life further.
Regular Swim Pants
Used for 2 to 8 weeks
Bought these for swimming at the local pool, after working out the sizing.
There lined at the front and have a draw string tie waist, which I have to say I have never really needed, especially with the waist being elasticated.
Though you can't really complain about them for the price, I found they had a heavy feeling and the waist band a little uncomfortable and deeper than some others.
They do have a flat front to keep you snug though.
Black Infinity Swimming
Used for 1 week or less
Colour, Fitting and Tightness
Good trunks
Used for 2 to 8 weeks
Good product just what I wanted for summer running
Good white trunk . Not see though
Really good quality
Used for 2 to 8 weeks
I like these very much! It is hard to find trunks in white and these fit really nicely.
Extremely well made and high quality, double lined
The double lining makes them very thick
Awesome Pair of Practical Trunks
Used for 2 to 8 weeks
Great trunks and if you feel comfortable wearing the brief style then these are the ones to have and they don't go transparent when wet.
Excellent Snug Fit, Feels great and comfortable
White Swimming Trunks
Used for 3 to 6 months
I needed some see-through swimming trunks for a corporate sponsorship that required printing on. These fitted the requirement. A previous pair of white swimming trunks let me down with being almost transparent when wet. As these are double lined no problem on that score. Comfortable to wear - although they appear to have too much material in the crotch.
Double lined so they do not go see-through.
Soggy when wet
These swimming trunks fit perfectly.
I have now used them on 10 occasions and am very pleased
made of a very good material
so far no problems
White swimming trunks
Was pleased as they are lined back and front so no issues with decency when getting out of the pool. They also sat more on my hips than waist which I quite liked. They are quite thickly lined so feel a little heavy and do not dry quickly, but do look good in white.
Good value and color
Takes a long time to dry
