What Our Gearhead® Experts Are Saying: "I’ve been riding in the Chrono Sport Jersey all summer, and it’s become my go-to. The fit is slightly relaxed but still aerodynamic, and the mesh panels are a lifesaver on hot days. I love that it uses recycled materials without sacrificing performance, and the pockets are roomy enough for snacks and tools." We pull on the Giro Chrono Sport Jersey when warm weather calls for lightweight comfort and effortless style. Giro built this versatile piece with Renew Series™ recycled polyester to reduce environmental impact without compromising performance. The slightly relaxed fit balances comfort and a streamlined look, making it easy to wear on spirited group rides or solo training sessions. Mesh side and back panels deliver powerful ventilation to keep us cool when the pace heats up, while the full-length zipper makes it easy to dump excess heat on big climbs. Three roomy back pockets handle everything from spare tubes to mid-ride snacks, and reflective details keep us visible when the miles stretch into the dusk.
