AERO BASE LAYER FOR AERODYNAMIC GAINS. If you have a keen eye, you'll have noticed the lines running down the arms of our pro riders when they race TTs. These aero ribs are our Bolero sleeves. The ribs create aerodynamic trip strips, making our Aero Jerseys and San Remo Speedsuits even faster. We've incorporated this short-sleeve version into a base layer for road racing. Not only will you be faster, but the open mesh of the base layer will keep you cool and dry.
