Heat wave No sweat. Combining class-leading aerodynamic design with highly breathable mesh, this is the ultimate high-performance summer jersey. Originally created for female professional riders looking for every possible advantage, this jersey uses a longer to-the-elbow sleeve, made from our exclusive PRO Transfer Aero fabric, and our patented Speed Sleeve construction. The combination smooths airflow around the bicep and over the shoulder to reduce aerodynamic drag and creates a sophisticated silhouette on the bike. A classic three back pocket layout is enhanced with our bellow design so you can comfortably load up for long days in the saddle.
