The RBX is a performance jersey from Specialized that's designed for all-day cycling, and the Specialized RBX Jersey + SWAT adds more storage for your full day. Its VaporRize fabric wicks moisture and dries quickly, and it feels comfortably soft and remarkably light. Stretchy mesh panels the back for airier ventilation and greater ventilation. Specialized fitted it close to the body without being too constricting to ensure comfort on long rides, and it has reliable sun protection necessary when the sun's out all day, too.
