Aries Spherical Bike Helmet

Item: 670049A2CR9
By: Giro


Cooler, lighter, faster, aesthetically and technically superior – you can have it all in the new Aries Spherical by Giro. This extra lightweight helmet utilizes all-new Spherical Technology powered by MIPs (Multi-Directional Impact Protection System) that allows the helmet’s outer liner to rotate around the inner liner during a crash. This combined with EPS foam dual layering increases overall cranial protection. The 24-wind vents maximize airflow while plush, antimicrobial padding and a network of deep internal channels elevate comfort. From the proven reliability and adjustability of the Roc Loc 5 fit system, to full lower hardbody coverage, to the highest production standards, the Aries is the epitome of top-shelf performance, protection and style.

Product Care

Helmets are made of materials that can be damaged by many commonly available cleaners. Petroleum based solvents or cleaners are especially problematic. They can damage a helmet so that its protective capabilities are reduced. Many times this damage is not visible. For best results, clean the helmet using a soft cloth or sponge, warm water and mild soap. Allow the helmet to air dry.
Please note, excessive heat can damage your helmet. For example, in direct sunlight, the interior of a car or dark gear bag can get hot enough to cause heat damage. Damaged helmets will appear to have an uneven or bubbly surface. When your helmet is not in use, we recommend you store it in a cool, dry place.
