The Castelli Seamless Short Sleeve Baselayer features three different mesh patterns, placing the most open mesh exactly where you need the most ventilation. The fabric throughout is as soft as it gets, and there are no seams to chafe or bind. The polypropylene/nylon blend pulls moisture away from the skin so you can ride hard in comfort.

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.
