Giro Aries Spherical Adult Road Bike Helmet


  • 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.
  • 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.
  • 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.
  • 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. 21 Wind tunnel vents.
  • 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.
