Training swimming shorts

For swimming training with some intensity I have been using Decathlon swimming shorts, from this product line, and so far they have been the worst version on sale: little resistance to chlorine, the perforations in the fabric (elastics) allow for greater stress of the fabric, causing it to tear more quickly! They didn't last 4 months! I'm careful with the maintenance of the material (I always rinse it thoroughly with running water after training and dry it in a controlled environment without UV rays) and I've never seen it deteriorate so quickly! I preferred the previous versions which are more resistant and durable! Thanks

Very very small size. It does not correspond to the size ratio.

Swimming jammers style

SWIMMING JAMMERS – 44 cm longThese JAMMERS are ideal for anyone who wants to surpass themselves. A 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.


Our engineers have developed a Polyester-based textile and replaced the elastane fibres with PBT fibres that give them 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.- even the brightest of colours will retain their colour-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.

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire life cycle using different indicators. An ABCDE score is provided to enable easy identification of the most environmentally-friendly products when comparing products of the same type (T-shirts, trousers, backpacks).Decathlon chose to apply this voluntary environmental labelling scheme.Web: sustainability.decathlon.comVideo:

Product testing

The products labelled 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, the product remains intact.

Storage instructions

Store the swim boxers in a dry place.
