The Eclipse Spherical is both the fastest road helmet and the coolest aero road helmet Giro has ever created, bringing our best technologies together in a light, compact form that's ideal for road and gravel racing. The sleek outer shell actively streamlines airflow to reduce drag across multiple wind angles, while 14 Wind Tunnel vents pull air through the helmet to provide incredible cooling power that rivals our most aggressively vented road helmets.
Inside, the ball-and-socket design of Spherical Technology is powered by the Mips® brain protection system, which allows the helmet's outer EPS foam liner to rotate around the inner foam liner during a crash to help redirect impact forces away from the brain. Progressive Layering of both the inner and outer liners help to offer more comprehensive protection, too. The patented Roc Loc® 5 Air system enhances stability and fit, and plush antimicrobial Ionic+ padding helps absorb sweat and moisture while providing durable antimicrobial performance.
Not only is Eclipse Spherical a big step up from the speed of our previously fastest aero road helmet, it is the fastest road helmet we have ever tested. We tested to measure helmet cooling efficiency and the results prove that Eclipse is almost as cool as our best-in-class road helmet, Aether Spherical.
