    From the elegant silhouette of its industrial design, to how this helmet manages impact forces, the Aether Spherical is a testament to performance innovation.

    Inside the Aether Spherical, 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 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.

    Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.

    Step 4: Adjust the interior pads if needed.

    Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.
