Castelli Pro Issue Sleeveless Base Layer
A big hit amongst Castelli's pro team ranks, the Pro Issue Sleeveless Base Layer is designed to provide comfort for those riders who are looking to spend a good long time in the saddle. The Pro Issue Sleeveless Base Layer is extremely effective at transporting moisture away from the surface of your skin - keeping you cool, comfy and dry.
Situated perfectly in the range between the Flanders Base Layer for chilly temperatures and the Core Mesh Base Layer for super hot rides, the Castelli Pro Issue Base Layer is the do-it all base layer, as well suited to spring rides in Belgium as it is to autumn rides around Lombardy.
