Castelli started the aero jersey revolution in pro cycling, and this jersey perfects it. The Aero Race 5.1 builds on their race-leading aerodynamics with updated Velocity fabrics on the front and back, resulting in a total 22 watt savings at race pace over standard jerseys. But it’s not just aero; it’s also extremely light, coming in at just 103 g. That’s almost as light as the Climber’s Jersey. The 3D Mesh back and sleeves will wick moisture away, keeping you dry and comfortable and making this the go-to choice even for cool- or wet-weather racing. Load the 3 rear pockets up, and the compression band around the pockets will keep your goods from going anywhere.
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.
