• Spherical Technology ball-and-socket design, powered by Mips®, helps redirect impact forces away from the brain
• Spherical Technology allows 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
• Giro helmets with Progressive Layering™ use 2 different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management
• All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards
• The goal of Giro Mips®-equipped helmets is to reduce rotational forces
• Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts
• Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power
• 15 Wind Tunnel vents provide exceptional cooling power
• 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, Roc Loc 5 Air allows cool airflow to pass directly over your head
• This further enhances the performance of vents and internal channeling that exhaust heat out of the helmet
• Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand
• IONIC+® padding; pure silver is the secret ingredient that gives IONIC® the power to provide natural, permanent odor protection to help keep your helmet feeling fresh
