The Aether MIPS is the perfect example of our 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. Inside the Aether, a dual-density EPS foam liner helps manage a wide range of impact energies, while also boasting deep internal channeling to provide cooling airflow. Our proprietary MIPS Spherical technology is integrated between the layers of EPS foam instead of against the rider's head giving riders the benefits of MIPS without obstruction to comfort or cooling power. The stunning silhouette is formed by a sleek six-piece shell that surrounds a series of massive vents, with added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is our Roc Loc 5+ Air fit system, featuring 3-way fit tuning, that allows for easy adjustment in seconds.
