Climber’s 4.0 Women’s Jersey

Castelli Climber’s 4.0 Womens Jersey

Castelli Climber’s 4.0 Womens Jersey has been meticulously crafted based on feedback from professional riders tackling the high mountains in scorching temperatures. Balancing aerodynamics with breathability, we’ve utilized CFD-based seam construction inspired by our Aero Race 7 Jersey, while incorporating the most aerodynamic 3D mesh fabrics available to ensure optimal cooling. These fabrics not only offer exceptional cooling properties but also boast a soft, stretchy texture for enhanced comfort during long mountain ascents. Additionally, the fabric on the back of the jersey provides reliable UV protection, blocking up to 90% of harmful rays, making it ideal for sun-drenched rides.
