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 27 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.

Lighter, cooler, sleeker, plus all the added protection of Spherical Technology powered by Mips and our new DryCore sweat management system: the Aries Spherical is like nothing before.

Key Features:

• The shatter‐resistant and translucent Aura II Reinforcing Arch runs throughout the helmet, bolstering structural integrity and allowing massive vents for cooling
• Researchers at independent testing facility Virginia Tech gave Aries Spherical their best score event in their rankings of which helmets best reduce the risk of injury. All Giro helmets with Spherical Technology have received their top level of 5 stars.
• 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.
• 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.
• 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.
• 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.
• Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.
• Giro helmets with Progressive Layering™ use two different density EPS foam liners to address high‐ and low‐speed impacts for more comprehensive energy management.
• Integrated eyewear docking ports with rubber grippers help to secure sunglasses.
• Reflective Details enhance visibility at nighttime or in low‐light conditions when illuminated by a light source, such as headlights, by returning the light back to the source and reaching the driver's eye.
• 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&reg 5, allowing you to easily custom‐tune fit tension and fore‐aft tilt of the helmet in seconds using a single hand.
• Pure Silver is the secret ingredient that gives IONIC+ ® the power to provide natural, permanent odor protection to keep your helmet feeling fresh.
