Nice trunks

Unfortunately had to return these as my son is very fussy and prefers a longer leg length. They seemed good quality however.

Good value swim trunks

They are good quality and although a little shorter than he was expecting my 9 year old son will wear them. Even though he is small in his class the age 10 was only just an ok fit. They will do the job though and for the money they are very good value. If I bought them again I'd go up 2 sizes.

Additional Product Information


Main fabric: 100.0% Polyester cationic ; Main lining: 100.0% Polyamide


JAMMER – 13” long (in size 10 years)The JAMMER is ideal for anyone who wants to surpass themselves. A swimsuit should primarily favor comfort. It should enable you to move with ease. That's why it is important to choose the cut of your swimwear carefully.


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.- Even the brightest of colors will retain their colorfastness.

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.

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.
