Fly Racing Formula S Carbon Helmets

Meet the Fly Racing Formula S, the world's first MX Smart helmet with integrated impact detection, emergency response, and real time ride analytics. The Formula S is one of the most innovative MX helmets ever created. This technologically advanced helmet combines intelligent telemetry with the best in helmet performance and safety. The Formula's Adaptive Impact System (AIS) is the result of years of collaborated research and design with industry-leading doctors, scientists, and physicists from around the world. AIS is a high-performance ecosystem of structural design and energy-mitigating materials. Each layer, from the RHEON-enhanced Energy Cells to the dual-density EPS liner, and the 12K carbon fiber shell, was carefully fine-tuned to achieve superior head protection from the widest possible range of real-world impacts. Available in solid colors or with cool graphic designs, in both adult and youth sizes. Key features: * ECE/DOT-approved * Adaptive Impact System (AIS) * 12K carbon fiber shell produces an extremely lightweight shell with superior penetration resistance * Impact Energy Cells made of RHEON, the Impact Energy Cells maximize absorption of low-speed linear and rotational impacts, reducing forces transmitted to the brain * Conehead EPS Technology provides a softer liner whereby the cones help manage or absorb an impact force more efficiently—six critical zones have been fine tuned for a progressive response to low-speed and high-speed impacts * Expanded volume EPS means strategic areas of the helmet have more impact absorbing EPS, more suspension between your head and the ground * Expanded Polypropylene (EPP) chin bar creates an additional element of impact mitigation, and is used in the chin bar for its superior damage resistance, and energy absorbing properties * Clavicle shell relief zone creates a soft zone filled with EPS and EPP to aid in reducing clavicle injuries * Custom molded rubber trim with integrated nose guard * Comfort liner and quick release cheek pads are made of washable moisture-wicking, anti-microbial material * True Functional Ventilation (TFV)-When in motion, air is forced through multiple air intake vents, then passed through aligned vent channels in the EPS and exits out multiple rear exhaust vents * Included premium helmet garage * Included extra visor
