Castelli Climber's A/C Jersey

Conquer the steepest mountain passes and brave the scorching sun with a feather-light cycling jersey designed specifically for use in the hottest conditions! The Castelli Climber's A/C jersey offers ultimate cooling without compromising aerodynamics, and so it is a favourite among professionals for sweltering mountain stages - it transforms your summer ride into a comfortable experience.

Composition and fit
The Climber's A/C jersey uses a strategic combination of Flusso 3D fabric on the front and StradaPro 3D fabric on the back for unrivalled breathability. The race fit is based on advanced CFD analyses, ensuring that the seams are positioned to minimise drag and that the fabric feels soft and stretchy against the skin. The jersey has been specifically developed for tropical temperatures between 22°C and 40°C, with the back panel also blocking over 90% of harmful UV rays to protect you on long climbing sessions in full sunlight.

Smart extras and high-quality finish
The finish of the Climber’s jersey is entirely focused on efficiency, which is evident in the elbow-length stretch sleeves with raw-cut ends for a seamless transition onto the arms. The Airflow shoulder construction ensures that the wind is optimally channelled past your body, even when you are sitting upright while climbing. At the back, three rear pockets offer ample space for nutrition, and the elastic around the waist perfectly supports the pockets and keeps the jersey in place. The YKK Vislon front zip is robust yet opens and closes smoothly so you can easily adjust ventilation and maximise it with a single simple movement.
