Jammers for men and boys Show your colours - swim with your brand The swimming brand ZAOSU is known for its colourful and eye-catching swimwear designs. With the new Z-Concept, ZAOSU remains true to this style. The brand name adorns the swimming trunks over a large area, making them an absolute eye-catcher in the pool. This unmistakable motif of bright colours sets the brand apart from other manufacturers. Just like the quality, which not only makes the jammers comfortable to wear, but also has low water resistance. The Z-Concept competition swimming trunks therefore live up to their brand name ZAOSU - which translates from Chinese as "lightning fast". You too can become ZAOSU! These swimming trunks are particularly suitable for children or masters swimmers looking for a light compression effect. They are FINA approved and can therefore be worn at competitions.
