We engineered the F3 Carbon Off-Road Helmet specifically to reduce fatigue and improve comfort over long rides, and ultimately to challenge what "light weight" really means. Built with ultralight hand-laid carbon fiber for the best consistency in shell thickness and resin distribution, F3 Carbon is the lightest ECE off-road helmet we were willing to make without sacrificing safety.
