We engineered the F3 Carbon Helmet specifically to reduce fatigue and improve comfort over long rides, and ultimately to challenge what "light weight" really means. A new, more aerodynamic and durable visor makes the second generation of F3 Carbon better than ever. Built with ultralight hand-laid carbon fiber for the best consistency in shell thickness and resin distribution, F3 Carbon is the lightest ECE snow helmet we were willing to make without sacrificing safety.
