Giro Eclipse Spherical MIPS Helmet Large Matte Black/Gloss BlackThe Giro Eclipse Spherical MIPS Helmet 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 Technology. 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 Ionic+ padding helps absorb sweat and moisture while resisting odors. Sizing Small: 51-55cm, Medium 55-59cm, and Large 59-63cm.
