The Giro Aries Spherical MIPS Road Helmet is the best-in-class high-end road helmet with a compact design that offers the pro tour riders every advantage they need to reach the top step of the podium. Its smaller form and lighter weight deliver sensational comfort and cooling power. Spherical Technology™, the ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. Twenty four Wind Tunnel vents are maximized by the AURA Reinforcement Arch, while plush IONIC+ anti-microbial padding and a network of intricately engineered deep internal channeling 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 the epitome of top-shelf performance, protection, and style. Spherical Technology's Ball-and-Socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin. Helmets with Progressive Layering feature a dual-density liner designed to address high and low-speed impacts, for more comprehensive energy management. Structural integrity is bolstered by the shatter-resistant and translucent AURA reinforcing arch that runs throughout the helmet. In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets. Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power. The revolutionary Roc Loc® 5+ Air fit system adds a new dimension to helmet performance by enhancing cooling as well as fit, comfort, and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, it allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet.
