The F3 Carbon Pro Helmet is engineered specifically to reduce fatigue and improve comfort on every ride, and ultimately to reimagine what "light weight" and "safe" really mean. KoroydA(R) is a next generation energy absorbing technology, engineered with a unique structure and innovative energy management properties. When impacted, the KoroydA(R) cores crush homogeneously, decelerating energy from an impact in a controlled manner. A custom visor design improves FOV while improving aerodynamics and strength. Built with ultralight hand-laid carbon fiber for the best consistency in shell thickness and resin distribution, F3 Carbon Pro is the lightest ECE snow helmet to carry this level of safety.
