Castelli's Body Paint Tri Women's Short Top has a tough role to fill. It's got to excel at three different disciplines requiring radically different ranges of arm and shoulder motion. It's also got to dry quickly in T1, maintain breathability and wicking, and minimize an athlete's aerodynamic footprint across the bike and the run. Since it's made with Castelli's Velocity fabric cut in a classic, abbreviated tri silhouette, the Body Paint Short Top manages to check all of those boxes. The material's high stretch allows for a seamless, painted on fit that reduces drag resistance, and a Prosecco treatment speeds evaporation from the swim to the run. The shorter body also eliminates the bunching up effect that other jerseys which fit well enough in the saddle tend to exhibit on the run.
