The Eclipse MIPS is both the fastest road bike helmet and the coolest aero road bike helmet that Giro has ever developed. It combines technologies in a lightweight, compact form that is ideal for road and gravel racing. The sleek outer shell actively redirects airflow to reduce drag at various wind angles, while 14 wind tunnel ventilation openings pull air through the helmet to provide incredible cooling performance that rivals the most aggressively ventilated road helmets. Inside, the spherical design of the Spherical technology is supported by the MIPS brain protection system, which allows the outer EPS foam lining of the helmet to rotate upon impact around the inner foam lining, directing impact forces away from the brain. The progressive layering of the inner and outer shell provides even more comprehensive protection. The patented Roc Loc 5 Air system enhances stability and fit, and the soft, antimicrobial Ionic+ padding absorbs sweat and moisture while providing lasting antimicrobial performance.
