Fly Racing Formula CC Helmet - Objective. ECE / DOT approved. Tri-weave composite shell is comprised of carbon fiber, DuPont™ Kevlar® and fiberglass, producing a 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® Dual-density Expanded Polystyrene (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.
