Fox Speedframe Helmet Solid Raising The Bar for Open Face Helmets The Fox Speedframe Camo Helmet is a highly-ventilated open-face helmet with safety and performance features not often found at this price point. The extensive ventilation is a product of large vent ports and internal channeling within the in-molded EPS foam construction, which directs airflow efficiently over the head-even during low speed climbs. The single-density EPS foam core helps to absorb impact forces, while revolutionary MIPS(R) technology features a low friction layer that greatly reduces rotational forces to the brain during certain types of impacts. A one-hand adjustable visor allows for the use of goggles for convenient, adjustable coverage and a removable, washable inner liner helps you keep the Speedframe fresh ride after ride.
