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.

Aerodynamics

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.)

Cooling Power

Helmet Comparison By Cooling Efficiency (%)
  • Aether 89.75%
  • Eclipse 89.25%
  • Competitor 88.64%
  • Helios 87.68%
  • Vanquish 85.13%

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).
