The Castelli Men's Pro Mesh Sleeveless baselayer is designed to facilitate moisture transfer through its ultralight airy construction. While most riders are aware the benefits a baselayer provides on a cold winter's ride, the extra layer is just as crucial during the hottest rides. Constructed from airy mesh fabric, the sleeveless form-fitting top wicks sweat away from the skin and uses it to help regulate core temperature.

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.

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.

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.
