Experience the next level of comfort and performance with the Castelli Pro Mesh 2.0 Men's Cycling Baselayer, available in White and Black. Designed using insights from WorldTour professionals, this premium sleeveless baselayer is engineered to keep cyclists cool, dry, and comfortable during high-intensity rides and hot-weather conditions. Whether you're racing, climbing mountain passes, tackling long endurance rides, or training indoors, the Pro Mesh 2.0 delivers superior moisture management and breathability, making it an essential foundation for every cycling kit.

At the heart of the Pro Mesh 2.0 is its advanced 3D open-mesh construction, developed to maximize airflow while maintaining exceptional moisture transfer. The highly breathable mesh fabric creates thousands of microscopic ventilation channels that continuously circulate air between your skin and outer jersey. This innovative structure helps dissipate excess heat, reduces sweat buildup, and maintains a comfortable body temperature even during demanding efforts under the summer sun.

Constructed from premium lightweight polyester performance fibers, the baselayer delivers outstanding moisture-wicking and quick-drying performance. Instead of absorbing perspiration, the hydrophobic fibers efficiently move sweat away from the skin toward the outer jersey, where it evaporates rapidly. This process keeps your skin dry, prevents overheating, and helps maintain consistent comfort during long climbs, intense training sessions, and endurance events.

The anatomical race fit is engineered to contour closely to the body without restricting movement. Its four-way stretch fabric follows every motion naturally, providing a second-skin feel that enhances comfort while maintaining a smooth profile under your cycling jersey. The low-bulk construction eliminates unnecessary fabric, allowing your jersey to fit perfectly while improving aerodynamic efficiency.

Designed with a sleeveless ergonomic cut, the Pro Mesh 2.0 offers unrestricted freedom of movement around the shoulders and arms. This design minimizes bulk beneath short-sleeve jerseys and improves ventilation in key heat zones, making it the perfect choice for summer riding, indoor training, and high-intensity racing.

The baselayer features flatlock seam construction, ensuring a smooth finish against the skin while minimizing friction and reducing the risk of chafing during long hours in the saddle. Every seam has been carefully positioned to enhance comfort and eliminate pressure points, allowing you to focus entirely on your ride.

One of the key performance benefits of the Pro Mesh 2.0 is its ability to create a microclimate between your body and jersey. By trapping a thin layer of air while rapidly transporting moisture away from the skin, it helps regulate body temperature across varying weather conditions. In hot climates, it promotes cooling through enhanced airflow, while in milder conditions it helps maintain comfort by preventing dampness and heat buildup.

Available in two versatile color options, White and Black, the Pro Mesh 2.0 seamlessly complements any cycling wardrobe. The White version reflects sunlight and pairs perfectly with lighter summer jerseys, while the Black version offers a sleek, understated look that matches darker race kits and training apparel.

The Castelli Pro Mesh 2.0 is ideal for road cycling, gravel riding, mountain biking, indoor trainer sessions, criterium racing, endurance rides, Gran Fondos, bikepacking, commuting, and daily training. Its lightweight construction and advanced ventilation make it especially effective in warm and humid conditions while remaining a valuable performance layer throughout the cycling season.

Manufactured with Castelli's legendary Italian craftsmanship, the Pro Mesh 2.0 retains its shape, elasticity, breathability, and moisture-wicking performance even after repeated washing. Built to withstand demanding use, it provides dependable comfort and professional-level performance ride after ride.
