Pro Level Base

The pro cyclists Castelli has worked with over the years know the importance of the right base layer for the conditions and that's where the Castelli Men's Pro Mesh Short Sleeve Baselayer comes into play.

The Pro Mesh is made for the widest range of conditions and is designed to keep you dry in cool to mild temperatures. We'll even put it under a Flanders Warm base layer in the coldest conditions. With a graphic print so you can show off that you have something special when you open your jersey zip.


  • 3D mesh fabric for excellent moisture management
  • Sublimated print graphic
  • Waist hem stays flat under shorts
  • Perfect for riding temperatures from 59° -80°F
  • Performance fit: Castelli apparel is designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you typically wear a Medium, select a Large in Castelli.

    Feel free to contact us with any questions or concerns.
