Castelli Bolero SS Base Layer

If you have a keen eye for detail, you may have already noticed the lines on the arms of our professional riders during time trials. These aerodynamic ribs are our Bolero sleeves. The ribs create aerodynamic turbulence strips that make our Aero jerseys and San Remo Speedsuits even faster. We have integrated this short-sleeve version into a baselayer for road racing. This way, you will not only be faster, but the open mesh fabric of the baselayer will also keep you comfortably cool and dry.
