Castelli Aero Race 5.1 Jersey

Castelli has been designing the fastest clothing for bike racers for more than a century. Castelli continued its successes by creating the Aero Race 5.1 Jersey FZ showcased by racers in today’s professional peloton. Castelli combined lighter weight and more compressive fabrics into the Aero Race 5.1 making it the lightest and most aerodynamic jersey ever designed by Castelli. This Italian company continues to provide cyclists with cycling clothing to give them an advantage whether they are racing with a number on their backs or matching efforts of other cyclists on a training ride. Castelli upgraded the fabric used on the front of the original Aero Race 5.0 jersey so the new 5.1 showed a 2 watt gain in the wind tunnel. The new fabrics also dropped 40 grams off the jersey’s weight. The Aero Race 5.1, weighing in at just 103 grams, provides a jersey that sits almost as light as air on a cycling body. The lightweight polyester fabrics on the front dry almost immediately while the 3D mesh on the back circulates air to keep a cyclist from being slowed down by body heat and sweat. Castelli placed a compression band around the waist to ensure the rear pockets don’t bounce around when loaded with riding food. The full-length YKK® Camlock zipper seals your body into this next-to-skin race jersey. The mesh arm bands with silicone gripper elastic are perfect for the shoulder area, the jersey arms stay in place and your sweat evaporates. Viz strips reflect sun rays so the jersey will not absorb heat, creating one more feature for a race jersey that keeps a rider comfortable when the heat is up.
