Features

  • 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.
  • 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 also debuts our revolutionary DryCore 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.
  • 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.

Description

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, Giro's ball-and-socket design powered by Mips, adds protection by redirecting energy away from the head 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.

  • Comfortable helmet that fits
Color: Matte White Size: Small
A comfortable helmet that fits the geometry of my head well without pinching or pressing in specific locations. The large vents are great, but for people with no hair, you definitely need a skull cap or good sunblock for protection from the sun. On bumpy roads, the helmet does slide a little forward when I wear a skull cap. However, this is not a defect with the helmet, but simply the fabric pads slipping on the fabric of the skull cap. I find one of the strap ends a little long and it flaps in the wind when going fast. May need to find a way to tuck it or cut off the excess. Overall, I'm happy with this helmet. ... show more
