Castelli Bolero Short Sleeve Base Layer T-Shirt White L

Aero base layer for use with Aero 7 Jersey and San Remo BTW Speedsuit for additional aero gains.

• If you have a keen eye, you'll have noticed the lines running down the arms of pro riders when they race TTs. These aero ribs are Bolero sleeves. The ribs create aerodynamic trip strips, making 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.

Features

• Open mesh body for optimal moisture wicking and airflow
• Sleeves with aero trip ribbing for maximal aerodynamic gain
• Temperature: 18°C - 35°C / 64°F - 95°F
