Giro Aether Spherical Road Helmet

From the elegant silhouette of its industrial design to how this helmet manages impact energy, the Aether Spherical is unlike any helmet ever created and a true testament to performance innovation.

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.

MEDIUM: 55-59 cm
LARGE: 59-63 cm

Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you've got the right size, you can adjust the fit.

HOW TO ADJUST THE FIT

Step 1: If the helmet has one, adjust the fit system at the rear of the helmet for a snug, secure fit. Some fit systems also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your
head.

Step 2: Adjust the straps so that they sit just below the earlobes.

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.
