Giro Aether Spherical Helmet

From the elegant silhoutte of it's 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.

SPHERICAL TECHNOLOGY

Spherical Technology's Ball-and-Socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.

AURA REINFORCING ARCH

Structural integrity is bolstered by the shatter-resistant and translucent AURA reinforcing arch that runs throughout the helmet

PROGRESSIVE LAYERING™

Giro helmets with Progressive Layering™ use two different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management.

DEEP INTERNAL CHANNELING

Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.

EYEWEAR DOCKING PORTS

Integrated eyewear docking ports with rubber grippers help to secure sunglasses.

ROC LOC® 5+ AIR FIT SYSTEM

This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling as well as fit, comfort, and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® 5+ Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc® 5, allowing you to easily custom-tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
