Technical Information

LONG BOXER – length 32cm, good mid-thigh coverage LONG BOXERS are ideal for those who prefer a shape with more coverage than regular boxer swim shorts. The fabric lies flat against the skin and the elastic tighter against the thighs ensuring good support, and allows legs to move without difficulty.
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.

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: http://sustainability.decathlon.com/

Used for 3 to 6 months
Bought these training for a 6-hour open-water swim, the bulk of training done in the pool. Although the shorts are XL and I'm only a 36inch waist, the fit, comfort and resistance of the shorts are top-notch. Certainly no skimping on materials, I anticipate these shorts lasting for years (I've already done about 10k open water in them and 40k in the pool and they're good as new).

Can't recommend them highly enough. Great value, too.
