HJC - F100 Modular Helmet - Reff - MC1
The F100 is HJC's fiberglass modular, built from a Fiberglass Composite shell that's lightweight yet highly impact-resistant. The Advanced Channeling Ventilation System combines aerodynamic and ventilation technologies, and a Compact Visor Mechanism keeps the shield's operation minimal and durable through an advanced rotation system. The HJ-45 visor offers 99% UV-A and UV-B protection and is Pinlock-prepared, while an adjustable sun shield mechanism extends 8mm for improved sun protection. A 3D contour design ensures a secure, comfortable fit, and the crown and cheek pads are removable and washable, lined with anti-bacterial fabric for enhanced moisture-wicking and quick drying. The visor itself is sized to the helmet — HJ-45A for XS-M, HJ-45B for L-2XL — for a properly proportioned fit across the range. In the Reff MC1 graphic, the F100 gives riders a lightweight, well-ventilated modular for everyday miles.
