Fly Racing began as a manufacturer of motorcycle handlebars and helmets. Since then, the brand has quickly developed into one of the fastest growing powersports apparel brands in the market. AIS - Adaptive Impact System. RHEON Impact Energy Cells which maximize absorption of low speed linear and rotational impacts, reducing forces transmitted to the brain. 12K carbon fiber shell - Produces an extremely lightweight shell with superior penetration resistance. Triple-density EPS provides a more progressive response to impact forces. Expanded volume EPS - Strategic areas of the helmet have more impact absorbing EPS, more suspension between your head and the ground. 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.
