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, impressive cooling power and sleek, compact shape would not be possible without AURA II.
  • Spherical Technology And Mips Protection System: Ball-and-Socket Design, powered by MIPS, redirects impact forces without compromising comfort, ventilation, weight or style. The market-leading protection system designed to address rotational motion, for an added measure of protection in certain impacts.
  • 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 riders 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 where it can evaporate more easily. 21 Wind tunnel vents.
  • 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 doesnt sacrifice speed.
  • Reflective Details And Eyewear Docking Ports: Reflective Details enhance visibility at nighttime or in low-light conditions when illuminated by a light source, such as headlights, by returning the light back to the source and reaching the driver's eye. Integrated eyewear docking ports with rubber grippers help to secure sunglasses.

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.

  • Perfect
Color: Matte Sharkskin Size: Medium
Great helmet, very solid and extremely comfortable, and looks awesome. This is coming from a guy who's tried pretty much every brand of helmet over the last 35 years!

  • Absolutely Great
Color: Matte Sharkskin Size: Medium
Similar to another reviewer, I was reluctant to switch out of my Aeon helmet, which has been phenomenal for riding (especially climbing) in the hot SoCal weather (certainly the lightest and best vented helmet I have ever owned). After the very first ride, I was relieved to find out that, despite the complex construction, this vents very very well and it is so comfortable that the extra grams over the Aeon are not noticeable in any way. The last part cannot be overstated enough in my case: the Aeon was wicked comfortable, yet this one is somehow better and has that "forget it's there" quality to it even after 4hr+ rides. It wraps around your head, yet it does not have the "pumpkin head" look. The only possible issue might be the integration with certain sunglasses: there is little margin for error before some arms may start rubbing the bottom. I ride with Sutro Lights and the integration is perfect to the point of not being able to tip the helmet much to the front or to the back. On the bright side, that forces you to wear it correctly. There have been zero issues after 6-700 miles and I hope it stays that way. The fact that it received the highest safety rating by Virginia Tech of any cycling helmet is reason enough to pick this over anything else, but throw in great comfort, great looks, and great ventilation, and this becomes a no-brainer. I am very very happy with it. ... show more
