Light and Compact Helmet Giro Eclipse Spherical ADVANCED PERFORMANCE FOR ADVENTURERS The Eclipse Spherical is both, the fastest road helmet and the coolest aerodynamic road helmet Giro has ever created, packing their best technologies into a lightweight, compact form that's ideal for road and gravel racing. The sleek outer shell actively streamlines airflow to reduce drag at multiple wind angles, while 14 Wind Tunnel vents pull air through the helmet to provide incredible cooling power that rivals our vented road helmets. Inside, Spherical Technology's spherical design 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 forces from the helmet. impact away from the brain. The progressive layers of the inner and outer linings also help to offer more complete protection. INCREMENTAL EARNINGS, EXPONENTIAL REWARDS Not only is the Eclipse Spherical a huge step up in speed from our fastest aero road helmet, the Vanquish, it's the fastest road helmet we've ever tested. Eclipse beats the closest aero road hull competitor by 14 seconds over 100 miles, and is a full minute faster than our very own Vanquish. (Average wind drag, combination of 80% typical riding position and 20% head down riding position).
