The Castelli Men's Core Mesh  was designed to be the perfect summer-weight base layer, working to provide constant moisture management beneath your jersey.

Constructed from Mesh fabric, Castelli opted to use only the most breathable polyester fibers to accelerate the rate of evaporation, ensuring maximum moisture management. With this base layer's next-to-skin fit, moisture transfer is constant and immediate for optimal temperature regulation. With a nearly seamless construction, chafing is kept to a minimum in this featherweight sleeveless garment.

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.
