We all know how crucial a solid baselayer is during those chilly winter rides, but just because the summer sun comes out that doesn't mean you should ditch the baselayer. Keep your core temperature regulated with the Castelli Men's Pro Mesh Sleeveless baselayer, constructed from tightly knit moisture-wicking mesh fabric.

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.
