Castelli Bolero SS Base Layer

Castelli’s Bolero Short Sleeve Base Layer helps improve performance with a fabric that wicks sweat, provides extra ventilation in hot weather, and delivers aero gains. The base layer’s body is made with an open mesh fabric made to evaporate body moisture and help keep you cool when racing in warm weather. The ribs on the arms provide further aerodynamics, making Castelli’s Aero Jerseys and San Remo Speedsuits even faster. When riding in Castelli’s Bolero Short Sleeve Base Layer, you will be faster, cooler, and drier for racing or training rides.
