The aerodynamic eclipse spherical is Giro's most sophisticated, stylish, and lightweight aero road helmet and it's crafted with spherical technology powered by MIPS®, so you can ride with more comfort and an additional layer of protection.
INCREMENTAL GAINS, EXPONENTIAL REWARDS
Not only is Eclipse Spherical a big step up from the speed of Giro's previously fastest aero road helmet, the Vanquish, it is the fastest road helmet Giro has 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 the Vanquish. (Wind Averaged Drag, combination of 80% typical riding position and 20% head down riding position.)
Giro tested with their proprietary Therminator head form to measure helmet cooling efficiency and the results prove that Eclipse is almost as cool as Giro's 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).
