Build the best offroad goggle out there. That was the goal when designing the 509 Sinister MX6 Fuzion Goggle. For aggressive dirt riders who demand fog-free clarity and maximum field of view, it boasts industry-first Fuzion lens technology that fuses Super Anti-Fog inner and outer lenses into one optically precise construction. The quick-latch system makes lens swaps easy. Strap outriggers provide a superior fit inside any 509 helmet. HCS (High Contrast Spectrum) spare lens tints available.
