Castelli Climber's A/C Jersey

Light. Dry. Fast.

Racing in the Alps in July is not for the masses, but the products that emerge from these experiences are fantastic for all of us. We designed this jersey for warm days in the mountains, based on feedback from professionals. They wanted a jersey that would keep them cool on hot days without sacrificing aerodynamics. The Climber's A/C Jersey uses the same CFD-based seam design as our Aero Race 8S Jersey, but we have utilized the most aerodynamic 3D mesh material we could find for optimal cooling. The material is soft and stretchy, providing a comfortable fit that you need for your days in the mountains. And since the jersey is made for sunny days, we also ensured that the material on the back blocks 90% of UV rays.
