Castelli Sidi Ar 4.1 Trøje

Traditionally, Castelli releases a special line-up for Sidi every summer. The Castelli Sidi Ar 4.1 cycling jersey has the same properties as the Free Aero Race 4.1 jersey but with a unique design featuring the Sidi logo. The Castelli Sidi Ar 4.1 is a great match to the Castelli Sidi Free Ar bibshort.

The Castelli Free Aero 4.1 jersey saves you 12 Watt of power at 40 kph in comparison to a regular jersey. Going faster without having to push harder, who'd say no to that? The combination of the Velocity and Nervato fabric offers breathability, great aerodynamics, and is quick to dry. In order to bring everything you need on your ride, the jersey has 3 rear pockets and 1 zippered pocket. The silicone gripper at the waist ensures this stylish jersey stays in place nicely.

Velocity Dry: this fabric is ideal for both dry and wet conditions since the lightweight polyester fabric dries up very quickly. Controlled stretch gives this fabric a luxurious and comfortable feel as well as an unmatched aerodynamic fit.
