In 2006 we took the industry by storm with the Sinister Goggle. 1,000,000 goggles later, constant refinement has resulted in a technological beast that sets the new bar. Featuring a 10% larger field of view than our X5, the 509 Sinister X6 Goggle’s dual component OTG (Over the Glasses compatible) Phantom frame allows for fast lens changes and a superior face fit when paired with any 509 helmet. Industry-leading optics offer the ultimate in anti-fog and anti-scratch performance coatings.
