HJC F100 Reff Adult Street Helmets
The HJC F100 Helmet is a versatile modular design built for riders who want comfort, convenience, and everyday usability. Its advanced fiberglass composite shell delivers a balanced combination of strength and manageable weight, while the rotational chin bar adds flexibility for commuting and touring. A Double D-ring closure ensures a secure, reliable fit.
The Advanced Channeling Ventilation System helps manage heat and humidity, while the Pinlock®-ready HJ-45 shield provides a wide field of view. An internal HJ-V12 dark smoke sun visor allows quick light adjustment on the move. Inside, a moisture-wicking liner and eyeglass grooves enhance comfort, and included features like a Pinlock® lens, chin curtain, and breath deflector make the F100 ready for everyday riding.
