Aries Spherical takes head protection to a whole new level – lightweight, ventilated and equipped with the most advanced technology we’ve ever put in a helmet.
- Spherical Technology Powered by MIPS – a revolution in protection
The two-piece shell connected by yellow elastomers acts as a hinge – when impact occurs, the hemispheres move against each other to absorb rotational and direct forces, while the Progressive Layering technology combines a harder outer and softer inner layer for maximum energy absorption. - Minimalist profile with maximum ventilation
The shape precisely follows the contours of the head, 24 Wind Tunnel holes ensure a continuous airflow – the result is a helmet you almost forget you’re wearing.
- Aura Reinforcement Arch
- Roc Loc 5+ Air retention system
- Ionic+ antibacterial padding
- Slimline lightweight straps
- In-mold, Nanobead EPS lightweight construction

Science and soul. They might seem like two disparate entities - but through the 30-year history of the Giro brand, they have been brought together in equal measure. Giro benefits from world-class resources. Based in Santa Cruz, California, it's an action sports paradise - incredible waves for surfers, endless singles for bikers and coastline-lined roads for roadies.
At Giro's headquarters, you'll find over 50 different helmet testers, several 3D printers, a custom wind tunnel, and even a Therminator test head equipped with thermal sensors to test helmet venting and hole placement. Giro has a lot of products in many categories, from helmets to gloves to trunks. But each one was born out of a desire to enhance your riding experience.
