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.

Nice fit, works great!

I bought this on the advice of a couple friends who swear by wearing base layers in the heat of summer. It's very lightweight and fits nice and snug, as is usual with Castelli. Does a great job of wicking away sweat and keeping you cool.

Breathable and comfy

This is a great product for riding in South Florida. It breathes easily and is very comfortable. I also use it for running and it provides me with a sense of safety as it is so loud.
