GIRO Aries Spherical Road Helmet Matte Black

Giro Aries Spherical Road Helmet Matte Black

A helmet that feels like it isn't there: the all-new AriesT 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 TechnologyT, 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 DryCoreT 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.

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 the risk of injury. It's the best performing helmet they've tested so far - even out-performing much bigger, bulkier helmets at reducing risk.

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. Aries also debuts our revolutionary DryCoreT sweat management system. A soft, silicone bead is hidden within the plush brow pad that redirects sweat away from the forehead and to the temples, where it can evaporate more easily.

STREAMLINED SPEED

When it comes to going fast, smaller truly is better. To craft Aries, we focused on reducing the frontal surface area to eliminate more 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.
