CASTELLI CLIMBER'S 4.0 JERSEY WHITE
Description
CASTELLI CLIMBER'S 4.0
Lightweight, Dry and Fast: the ultimate jersey for high mountains and extreme heat conditions, where every gram and every degree counts.
The Climber's 4.0 was developed with a clear objective: to keep professional cyclists cool on the hottest days of the Tour de France without sacrificing aerodynamics. Using state-of-the-art moisture-wicking fabrics, this jersey ensures you stay light throughout the climb, offering a cooling capacity that seems impossible even to put on.
CFD Technology and Elite Performance
Through computer simulations (CFD), Castelli optimized airflow, making it as fast as the Aero Race jersey on flat terrain, but with unbeatable breathability. Flusso 3D fabric in the front and StradaPro 3D in the back work together to instantly wick away sweat. With aerodynamic laser-cut sleeves and a race fit, this is the tool of choice for conquering the highest peaks under the scorching sun.
