If you're in a race, then you probably know the benefits of aerodynamics. Being aerodynamic while you're riding can save you energy so you can finish the race stronger. The Castelli Free AR 4.1 Jersey FZ has velocity dimpled fabric on the front and shoulders for improved wicking and faster drying and Nervato fabric at the armholes for improved aerodynamics. This jersey saves approximately 12 watts at 40 km/h compared to a normal race-fit jersey. It features a full-length YKK Vislon zipper and neck protector that improves the ventilation, silicone gripper elastic at the waist, and mesh raw-edge arm grippers. The 3 rear pockets make it easy to carry your riding essentials and the zippered rear pocket holds an item securely. With reflective heat-transfer viz strips, you'll have increased visibility in low-light conditions.
