The newest in Castelli's line of revolutionary aerodynamic jerseys, the Aero Race 5.1 saves 2 watts and sheds 40 grams over its predecessor. The new and improved Velocity fabric makes up the front of the jersey, using a featherlight blend of fibers that channel air over your shoulders across its dimpled surface. The sleeves and back continue the dimpling with the 3D mesh fabric, wicking moisture from your skin and keeping you cool through the hardest efforts. Not only is this jersey incredibly fast, it's incredibly lightweight at just 103 grams.
Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.
