Castelli Climber’s A/C 2026 short-sleeved cycling jersey

Designed to help you climb faster when the heat sets in, the Castelli Climber’s A/C Jersey is the epitome of lightness and coolness. Worn by riders from the Soudal Quick-Step WorldTour team during mountain stages or on hot days, it has been designed to offer maximum cooling on long, demanding climbs.

The ultra-breathable 3D Flusso and StradaPro fabrics on the front and back allow air to circulate continuously, whilst the fluid dynamics-inspired construction optimises aerodynamics without sacrificing comfort. The elbow-length, raw-cut sleeves provide excellent support whilst remaining discreet against the skin. A jersey designed for the mountains and hot weather, when every gram and every watt counts, without compromising on safety thanks to its UPF 13 UV protection.
