Versatile comfort.

The Castelli Pro Mesh Short Sleeve Baselayer offers more comfortable riding in cool-to-mild temperatures. With its 3D Mesh fabric construction, the Pro Mesh Short Sleeve Baselayer offers excellent moisture management, turning perspiration and moisture to cool the rider, staying cool and dry. A comfortable design features minimal seams and hems that lay flat under a jersey or bib shorts. Sublimated graphics offer a pop of color under a jersey.

Note: Castelli tops and bottoms are 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 normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.


  • Versatile short sleeve design works well in mild to cool temperatures solo, or under a heavier baselayer for colder rides.
  • 3D Mesh fabric for excellent comfort and superior moisture wicking.
  • Waist and arm hems stay flat under shorts and jersey.
