A NEW ICON RISES
How do you make the best better? That’s the challenge our designers and engineers faced when creating the successor to the Aether. And with the Aries Spherical, they’ve truly outdone themselves. Lighter, cooler, faster – and all in a smaller, sleeker form that is both fresh and clearly a Giro design. It’s our most premium helmet ever and a true object of desire. From Pro Tour professionals to riders breaking away on epic gravel adventures, Aries Spherical is the helmet everyone is going to want.
A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its smaller form and lighter weight (only 265 grams in size medium, CE certification), delivers 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 the epitome of top-shelf performance, protection, and style.
STRUCTURAL INTEGRITY
The proprietary AURA II Reinforcement Arch makes everything possible. These shatter-resistant, translucent twin bridges run throughout the helmet, providing structural integrity without adding unnecessary weight. Aries’ ultra-low weight (~5% lighter than Aether,) impressive cooling power and sleek, compact shape would not be possible without AURA II.
SPHERICAL TECHNOLOGY
This unique ball-and-socket design, powered by Mips®, helps redirect impact forces. Spherical Technology also boasts more comfort, improved airflow, and Progressive Layering (which mates two densities of EPS foam to address a wide range of impact energy). The results are clear: independent authority Virginia Tech has rated Aries #1 in reducing risk of injury.
NUMBER ONE RANKING
Researchers at independent testing facility Virginia Tech ranked Aries Spherical #1 in reducing risk of injury. It’s the best performing helmet they’ve tested so far –even out-performing much bigger, bulkier helmets. All Giro bike helmets with Spherical Technology have received Virginia Tech’s top-level rating of 5 Stars.
STREAMLINED SPEED
When it comes to going fast, smaller truly is better. To craft Aries, we focused on reducing the frontal surface area to reduce drag. Add in tiny details like chamfered edges on the AURA II, and meticulously engineered internal channeling that actually speeds up the air as it exits the helmet, and Aries emerges as the climbing helmet that doesn’t sacrifice speed, reducing aerodynamic drag by 4% over Aether Spherical.
COOL COMFORT
Deep internal channels connect with Aries’ massive front and rear vents. This system provides a path for cool air to flow over the rider’s scalp and exit the rear, taking excess heat with it. Aries outperforms our previous cooling benchmark, the Aether, with a 2.3% improvement in cooling efficiency.
DRYCORE TECHNOLOGY
To further boost comfort, Aries debuts our DryCore™ sweat management system. This unique pad innovation utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.
