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.

Reviews
The Castelli Climbers 4.0 short sleeve jersey is absolutely fabulous. To date this beautiful SS jersey is my favourite top to cycle in. It's my favourite because I feel it fits me perfectly - fits tight but comfortable, seems very aero. No creeping up on my arms or from the waist. The elastic inner rubber band makes the jersey stay put. 3 pockets of which my pixel phone fits. ( I'm XS size). The red/orange/yellow colour is nice and bright which I like for the roads. Good zip and as always the Castelli logo and I particularly like the Castelli logo on the shoulder. Yes 10/10. Well done Castelli and Sogma. Thank you.
