The Eclipse Spherical is a standout aero road helmet that brings their 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 their 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 anti-microbial performance.
