This long-sleeved jersey is specifically designed for running and intense training in mild winter temperatures and cold (5°C-18°C), bridging the gap between aerodynamics and thermal insulation. The bodyfit cut is performance-oriented but not as aggressive as our Race Proven jerseys. The jersey is made entirely from Tempest by Bioracer, an insulating and breathable fabric with a water-repellent treatment. Tempest is warm enough to protect against cold, wind, and rain, yet light enough to prevent the cyclist from overheating as temperatures rise. If you are looking for a jersey that keeps you dry and secure all day, regardless of your riding style or conditions, then this is the right choice for you.
