Keeping us cool, calm, and comfortable, Specialized's Prime Short-Sleeve Jersey is what we zip up to enjoy the road ahead when warm temps are in the forecast. This jersey employs a stretchy, cooling fabric blend for thermo-regulating performance on sweltering summer days, along with a full-length VISLON zipper to help release excess heat in a pinch. Three rear pockets safely stow our gels, cash, and mini tools, while the UPF 30 sun-protection rating helps defend our skin from harsh UV rays.
