Excellent durable swim trunks.

Good value hard wearing trunks. Sizing is a bit peculiar - I'm a 34'' so bought a size 44 which fitted well.

I don't have to keep adjusting the trucks and they don't sag at the back.

Super plavky

Krásné, ALE...

Plavky krásně sedí i vypadají, ale po jediném použití se na zadku jaksi třepí vlákno. Vypadají, jako by byly odřené, přitom jsem s nimi neseděl na ničem hrubém, ani nejezdil po tobogánu.

Preis/Leistung absolut Top...

Etwas zu klein geraten für die sonst gewohnten Decathlon Größe...

icon-circle-checkmark verified purchase
Gutes Preis Leistungs Verhältnis

Ich Schwimme mindestens 3 mal pro Woche und bin mit Design und Funktion sehr zufrieden. Die Größe habe ich entsprechend dem Größenberater gewählt, anfangs war sie sehr eng hat sich aber etwas geweitet.

Additional Product Information


Main fabric

  • 100% Polyester cationic


  • 100% Polyamide


SWIMMING TRUNKS – side height 2.75 in. First and foremost, a swimsuit should be comfortable. It should enable you to move with ease. That's why it is important to choose the cut 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 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. - UV resistant: 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.


Swimwear intended for regular use.
