Bringing Castelli's best watt-shaving technology to young riders, the Aero Kids' Jersey benefits from CFD-based fabric placement and seam construction, for improved aerodynamics. The shoulders, too, are constructed to be aero, while raw-cut, elbow length sleeves deliver supreme comfort.

The jersey is also eco-friendly, having been constructed using sustainable fabrics. Thanks to the inclusion of a full length, easily vented zipper, elastic that holds the waist in place and sturdy pockets, it is both practical and easy to wear.
