Product Details

A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power.

Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management.

24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style.

• Aura II Reinforcing Arch: The shatter-resistant and translucent Aura II Reinforcing Arch runs throughout the helmet, bolstering structural integrity and allowing massive vents for cooling.
• Drycore™: The DryCore™ sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.
• 24 Wind Tunnel Vents: Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust cool, fresh air over and around the rider’s head while forcing heat and stale air out.
• Deep Internal Channeling: The inner liner of the helmet is aggressively engineered to assist air flowing through the helmet, working in conjunction with our Wind Tunnel vents to provide an easy pathway for cool air to flow in and hot air to exhaust out.
• 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.
• Eyewear Docking Ports: Integrated eyewear docking ports with rubber grippers help to secure sunglasses.
• 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.
• MIPS® Brain Protection System: All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.
• Weight: 265g (Medium)
