509 Sinister X6 Fuzion Lenses

509's industry-first Fuzion Lens combines the inner and outer lenses of a traditional dual-panel lens into a fused and bonded single pane ventless lens. Designed specifically for high speed, high octane trail riding that requires a maximum field of view.

Eliminating the lens gasket and fusing the Super Anti-Fog inner and PC outer lens into one optically clear, the ventless lens provides an unmatched field of view with less diffusion.
