MTB Cycling Jersey
High-stretch breathable mesh fabric with anti-snag and moisture-wicking performance, designed specifically for the dynamic demands of mountain biking. The bright color scheme creates a strong visual contrast against natural terrain, enhancing visibility on the trail.
The side sleeve panels and rear hem use spliced fabrics to help resist mud and dirt stains from rugged mountain roads. The underarm area features a large printed graphic inspired by the landscape scenery riders experience while racing through gravel, dirt, and rocky terrain.
The overall design reflects the spirit of off-road cycling, combining functionality, durability, and expressive trail-inspired aesthetics.
