Castelli took their Aero Race 4.0 Jersey FZ to the wind tunnel and discovered that it saves 12 watts at a speed of 25 miles per hour. 12 watts is an entire season of training! Keeping the jersey locked in place and wrinkle-free for optimal aerodynamic stealth, it's aero features include Velocity Dry paneling on the front and shoulders, Nervato fabric at the arm, Giro3 elastic cuffs, and an elastic waist gripper. With excellent wicking, breathability, stretch, and a full-length zip, the Aero Race 4.0 is a great choice for virtually every condition and every type of rider.
