Research has proven that 37°C is the optimal core body temperature for riders to deliver power and remain comfortable. Regulating rider body temperature across changing weather conditions and varying intensity levels is uniquely challenging. SHIMANO 37°C is designed as a year-around system to help optimize rider comfort and efficiency.

With 37°C, we factor in things that are controllable – moisture management, wind penetration, and intensity – based temperature regulation, with things that can’t be controlled – like changing temperature and weather conditions. 37°C utilizes unique combinations of insulating and wind/water blocking fabrics, Dynamic Layering, and strategically placed ventilation.
