Castelli Free Aero 4.1 Jersey

The Castelli Aero Race 4.1 is the predecessor of the Aero Race 5.1, but Castelli chose to keep the 4.1. This because it's still the most comfortable allround jersey Castelli ever made, plus it's still one of the most aerodynamic jerseys on the market. The Free Aero 4.1 Jersey saves you around 12 watt at 40 km/h compared to a normal jersey. Perfect fit and excellent moisture regulation with fresh design.

Technologies:

Velocity Dry: this fabric is perfect for dry and wet conditions, because the lightweight polyester is dry in seconds.
