Better wicking, better fitting and easier to use, the Free Aero Race 4.0 Jersey is one of the most aerodynamic jerseys in Castelli's line. New Velocity Dry fabric with Aero technology is highly breathable, quick-drying and saves 10-12 watts at 25mph -- that's 35-40 seconds gained per hour. Updated stretch panels give you a great fit, full zip makes ventilation a cinch, and Giro3 arm bands with Nervato underarm inserts keep you streamlined. Silicone gripper hem stays put when you're down in the drops and three back pockets hold race-day essentials.
