Giro Aether Spherical Bike Helmet

The Giro Aether™ Spherical helmet combines an airy, open design with a revolution in rotational impact energy management to increase the level of protection for the rider's head. Inside this bike helmet, two different layers of EPS foam can handle a wide range of impact energies, while the internal channelling system allows for great cooling.

Exclusive Spherical Technology™ is integrated between the two layers of EPS foam -that is, directly in contact with the scalp- giving riders the benefits of MIPS without any interference or overlap with the 21 ventilation holes.

On the outside, a six-piece Hardbody™ polycarbonate shell creates a clean, aerodynamic silhouette around the ventilation holes, which gets additional structural reinforcement thanks to the super-strong AURA reinforcement arch. The final touch is the Roc Loc® 5+ Air fit system, which offers easy adjustments in seconds for an extra level of comfort on your bike.
