Castelli Climber's 3.0 SL2 Cycling jersey (M, grey) - The aerodynamic road jersey for hot temperatures and steep climbsThe Climber's 3.0 SL2 from Castelli is a road cycling jersey specifically designed for hot temperatures and high intensity rides! The Flusso 3D fabric used on the front and sleeves is interspersed with mesh fabric to ensure sufficient ventilation. On the other hand, the StradaPro 3D fabric on the back focuses on breathability and moisture management, and is also extremely quick-drying. In addition, according, to the manufacturer, the back material is supposed to block harmful UV radiation. Material selection and their placement, as well as the seams, are based on CFD analyses. As a result, the jersey is fantastically aerodynamic despite all of its features that deal with heat and solar radiation. With that in mind, it makes sense that the pattern of this jersey also follows that of the Aero Race Jersey.The weight of the Climber's 3.0 SL2 is almost completely negligible - just 106g in size M! This extremely low weight makes the shirt ideal for mountain goats who can’t find climbs steep enough. Last but not least, the jersey fits like a glove, while the open cuffs ensure that no seams leave you chafed or get in your way.
