The Aether™ Spherical 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 to manage a wide range of impact energies, while also boasting deep internal channeling to provide cooling airflow. Our proprietary Spherical Technology™ is integrated 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 six-piece shell forms a stunning silhouette around the massive vents, which get added structural reinforcement via a shatter-resistant AURA reinforcing arch. The final touch is our Roc Loc ® 5+ Air fit system, featuring three-way fit tuning, that allows easy adjustment in seconds for the ultimate in comfort.
