Aero helmets are tricky to choose owing to a variety of attributes such as ventilation, fit, and comfort - not to mention their aerodynamic claims, which are the primary selling point. Having tested hundreds of helmets, including myriad time-trial options, I can confidently say fit and comfort are non-negotiables, and Giro has always delivered in this regard. The company has been manufacturing some of the best road bike helmets for over 40 years and, in that time, has forged a reputation for balancing all the aforementioned attributes.
The original Eclipse helmet was one of Giro's best aero helmets. While packed with comfort, safety tech, and ventilation, the current obsession with going faster prompted the company to re-examine the Eclipse platform to make it even slipperier than before, and the result is the helmet you see here - the Eclipse Pro.
