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.

  • The Helmet I Hope to Never Truly Review
Color: Matte Black Size: Large
This helmet is light as a feather, super comfortable, and so well-fitted that I barely notice it's there. It looks great, too - like I actually know what I’m doing on a bike. Now, as for safety… let’s just say I really hope I never have to put that to the test. But for now, it’s a solid buy!

  • Great helmet

Easy to adjust for a snug fit. Good ventilation.

  • Very comfortable
Color: Matte Black Size: Large
Bought it because it was the top rated helmet for safety by a major university. Fits great, comfortable and looks good. Expensive, but I'm on my bike everyday and safety is paramount

  • The safest out of 238 helmets tested by Virginia Tech
Color: Matte Black Size: Large
I value having the lowest risk of brain damage in case of an impact so I picked this helmet. It's incredibly light and comfortable.

  • Great Helmet
Color: Matte Black Size: Large
I bought this helmet to replace a Giro helmet that was well past its expiration date. The helmet fits well, looks great, and is very light. It’s on the pricier of sides, but you get what you pay for.
