About the Giro Aether Helmet The Aether represents the pinnacle of Giro\\\'s tenacious approach to pushing the norms and striving for more. The Aether™ MIPS is the perfect example of Giro\\\'s commitment to perpetually pushing for better. From the elegant silhouette of the Aether\\\'s industrial design to how this helmet manages impact energy, it\\\'s unlike any helmet ever created and a testament to Giro\\\'s dedication to leading head protection. Three years in the making, the Aether MIPS combines airy, open design with a revolution in rotational energy management to advance head protection for cyclists. Key Features: > 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. . > Proprietary MIPS Spherical technology is embedded 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 6-piece shell forms a stunning silhouette around the massive vents, which get added structural reinforcement via a shatter-proof \\\"halo\\\" that runs throughout the helmet. > The final touch is Giro\\\'s Roc Loc® Air fit system, featuring three-dimensional fit tuning, that allows easy adjustment in seconds for the ultimate in comfort.
