A premium off-road helmet, the Fly Formula Carbon motocross helmet boasts a 12K carbon fibre shell that is extremely lightweight and has superior penetration resistance. It also offers Impact Energy Cells made of RHEON. The Impact Energy Cells maximise the absorption of low-speed linear and rotational impacts, reducing forces transmitted to the brain. Fly's 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. In addition, expanded volume EPS-Strategic areas of the helmet have more impact-absorbing EPS, giving more suspension between your head and the ground for superior protection, and the EPP chin bar with expanded polypropylene creates an additional element of impact mitigation. The shape of the shell allows for a clavicle shell relief zone - a soft zone filled with EPS and EPP to aid in reducing clavicle injuries. The Formula 21 also comes with a custom moulded rubber trim with an integrated nose guard and a comfort liner, as well as quick-release cheek pads made of washable, moisture-wicking, anti-microbial material. It also benefits from Fly's True Functional Ventilation (TFV), where air is forced through multiple air intake vents, passed through aligned vent channels in the EPS and exits out multiple rear exhaust vents for enhanced airflow. It also offers lightweight custom visor screws and titanium alloy D-rings for secure and adjustable closure. Also available in other colours.
