Introducing the Pro SL 3-season Jacket, built for hardcore road riding from autumn through winter and into spring. A unique ventilation system with air intake and exhaust points helps stop your inner engine from overheating. The outer shell uses a mix of high stretch, waterproof membrane fabrics, and it comes with a separate inner gilet made from PrimaLoft® Evolve fabric in strategically positioned panels for lightweight insulation when temperatures drop. The venting system is designed for thermal control on the bike. Long, 2-way front facing zipped vents draw air in even at low speeds or when you are pushing hard and low on the drops. A rear exhaust vent drives airflow around the body to help dry and regulate temperature, and wrist vents add another cooling option by exposing a heat sensitive area that can noticeably affect core temperature. The optional inner gilet can be worn for colder conditions or lower intensity rides. PrimaLoft® Evolve provides the lightweight insulation of a PrimaLoft® fill without needing to be sandwiched between inner and outer shell fabrics, with wicking and drying performance.
