The fastest jersey Castelli has ever made just got even faster. Built on the race-proven aerodynamics of the Aero Race 5.0, the Castelli Aero Face 5.1 FZ Jersey is more comfortable and durable, plus it boasts a 2-watt gain in the wind tunnel. Velocity dimpled fabric with Aero technology is highly breathable, quick-drying and saves 22 watts at 25mph -- that's about 88 seconds gained per hour! It's also extremely light, coming in at just 103g. That's about 40g lighter than a standard jersey and almost the same weight as the Climber's Jersey, yet it's significantly more aerodynamic. Mesh back panel features a 3D structure that lifts the fabric off the skin for improved wicking and reduced cling. Full YKK zip provides great ventilation and easy on/off while the Air Mesh arm bands keep you cool and streamlined. Silicone gripper hem stays put when you're down in the drops and there's a compression band around the back pockets to prevent them from moving or bouncing when they're loaded up. The Aero Race 5.1 FZ is your go-to piece for aerodynamics and fast-drying comfort.
