Built upon the world’s most legendary goggle platform, the 509 Sinister X6 Fuzion Goggle is for aggressive trail riders who demand maximum field of view. Industry-first Fuzion lens technology fuses Super Anti-Fog inner and outer lenses into one optically clear, ventless construction. The Fast Lens Loading System makes lens changes a breeze. The Phantom frame is extra wide to disappear from your line of sight, while strap outriggers provide a superior fit inside any 509 helmet.
