The Aether™ Spherical combines airy, open design with a revolution in rotational energy management to advance head protection for cyclists. Inside the Aether, a dual-density EPS foam liner helps to manage a wide range of impact energies, while also boasting deep internal channelling to provide cooling airflow.Our proprietary Spherical Technology™ is integrated between the layers of EPS foam—instead of against the rider’s head—giving riders the benefits of MIPS without any obstruction to comfort or cooling power. Outside, a sleek six-piece shell forms a stunning silhouette around the massive vents, which get added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is our Roc Loc® 5+ Air fit system, featuring three-way fit tuning, that allows easy adjustment in seconds for the ultimate in comfort.

SPEED WITHOUT COMPROMISE 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. INCREMENTAL GAINS EXPONENTIAL REWARDS Not only is Eclipse Spherical a big step up from the speed of our previously fastest aero road helmet the Vanquish it is the fastest road helmet we have ever tested. Eclipse beats the closest aero road helmet competitor by 14 seconds over 100 miles at 25mph and is a full minute faster than our own Vanquish. (Wind Averaged Drag combination of 80% typical riding position and 20% head down riding position.) CONFIDENTLY COOL We tested with our proprietary Therminator head form to measure helmet cooling efficiency and the results prove that Eclipse is almost as cool as our best-in-class road helmet Aether Spherical setting a new standard for aero road helmets. (Cooling measured from 100º starting temperature at with 25 mph wind speed).
