Kedves Gergely!

Köszönjük, hogy értékelted a termékünk, egyúttal sajnálom, hogy nem nyerte el a tetszésed.

A 900-as boardshortjaink technikai anyagból készülnek, annak érdekében, hogy e sportot űzők minden igényét kielégítse.

Nagy mértékű rugalmasság és gyors száradás érdekében készült poliészterből és elasztánból.

Ennek egyik kellemetlen mellékhatása lehet a bőrre tapadás, azonban cserébe sokkal gyorsabban megszárad mint egy alacsonyabb kategóriás termék.

Remélem segítettem, és továbbra is vásárlóink közt tudhatunk.

Sportos üdvözlettel!

taglie piccole

preferibile una tg in piu' per maggior comodità, tessuto elastico comodo e finalmente un po' di colore!. Opinioni: pantaloncini leggermente sopra il ginocchio, un po più lunghi sarebbe meglio. Tasca laterale minuscola e apertura laterale a mio avviso scomoda

Foarte tare

Foarte bun.

What are boardshorts?

Boardshorts are swimming shorts and more generally a style of swimsuit for men and, more recently, for women. They were created in the 1950s for surfing. Over past years they have become a popular style of swimming suit. The name "boardshorts" comes from their use in water sports using a board, such as surfing.

What is the olaian brand?

OLAIAN, DECATHLON'S SURF BRAND. Based in Hendaye, in southwest France, OLAIAN is Decathlon's surfing brand. In our offices at the water's edge, we can design a pair of boardshorts and then on the same day go surfing and test them to check that they stay in place in the waves and are comfortable and durable!
