Castelli Climber's 4.0 Jersey CS240066255

Castelli Climber's 4.0 Jersey  Racing in the Alps during July is typically reserved for a select group, but the innovations stemming from such experiences offer tremendous benefits to a broader audience. Introducing Castellis Climber's 4.0 Jersey was driven by the need for performance in hot mountainous conditions, informed directly by professional input. Athletes sought a jersey capable of effectively managing temperature without compromising aerodynamics in warm climates. Leveraging the CFD-based seam construction found in our Aero Race 7 Jersey, this jersey integrates advanced 3D mesh fabrics renowned for their exceptional aerodynamic properties and optimal cooling capabilities. These fabrics boast a soft and flexible texture, ensuring a comfortable and unrestricted fit crucial for enduring challenging mountain rides. Moreover, mindful of prolonged sun exposure, the jersey features fabric on the back that effectively blocks up to 90% of harmful UV rays.
