The Sinister X5 Goggles by 509® have a completely redesigned frame to provide the absolute maximum field of vision and to slope perfectly to the contours of your face, while minimizing the amount of frame in your field of view. Permanent fog free coating on a dual Polycarbonate (PC) anti-scratch lens. Removable nose mask that was restyled to be oversized and removable to keep you warm and comfortable. 0.5" taller than the traditional Sinister goggle, giving you the best vision possible. Perfect fit outrigger system that moves the strap mount points forward, giving you a better seal against your face with evenly applied pressure. Replacement lenses are available (sold separately).
