Giro Aries Spherical Helmet

Giro Aries Spherical Helmet

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 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.

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.
