Key Features INTEGRATED MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giros 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 the riders brain in certain impacts. ROLL CAGE REINFORCEMENT — Roll Cage is a light-yet-tough web of reinforcement invisibly molded inside a helmets EPS foam liner. It helps the helmet to hold together under impact; and provides an extra measure of strength and integrity that youll never notice ... unless you need it. WIND TUNNEL VENTILATION — Giro helmets are developed utilizing our proprietary Wind Tunnel ventilation system. This elaborate design combines active vents in the helmets shell with exhaust channels inside the helmet that thrust fresh; cool air over and around the riders head while forcing heat and stale air out. Its the most effective cooling system available; and a difference you can feel every time you ride. ROC LOC® 5 AIR MIPS FIT SYSTEM — In addition to helping to optimize stability and cooling airflow through the helmet; the micro-adjustable ergonomic and compact dial allows riders to adjust vertical positioning and tune the contact points independently for a customized fit with exceptional comfort. IONIC+® PADDING — Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural; permanent odor protection to keep your helmet feeling fresh.
