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. Giro's 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 Giro's Roc Loc 5+ Air fit system, featuring 3-way fit tuning, that allows for easy adjustment in seconds.
