    1. STYLE
      JAMMER – length 33 cm (in size 10 years) 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. The Jammer provides great muscle compression for the quads and glutes, resulting in the perfect fit.
      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.
    4. USE
      Swimwear intended for regular use.
    5. 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, trousers, backpacks, etc.). Decathlon chose to apply this voluntary environmental labelling scheme. For more information, visit:

    • Excellent swimwear

      Karen (United Kingdom)
      Used for 1 week or less
      Lovely patterned swimwear. Washes well and comfortable after all the labels were removed. My son feels they help him swim fast in the water.
      Sadly, as with a lot of the children's clothes they measures small so my standard sized age 10 year old fits age 14 with no more children's sizes to progress to after that.
      Would welcome the introduction of more child sizes across all your ranges.

      Response of the brand
      Hi Lorri,

      Thanks for your message and apologies for your experience with the sizing of the product. Unfortunately we do find that some of our textiles (and in particular the junior ones) come up slightly small compared to usual UK standards (we work from a EU size). Also we are working towards offering free delivery on exchanges for all online purchases, hopefully to be introduced next year. 
      Once again apologies for the inconvenience you experienced.
