509 Sinister MX6 Goggle

The 509 Sinister MX6 Goggle is a rugged beast that brings everything we’ve learned about optics to offroad. Featuring a super-wide field of view, it’s engineered for dirt with an extra-tough outer lens that fights fogging and scratching with high-grade coatings. A quick-latch system makes lens changes easy, while tear-off posts are a must for race day. Outriggers on the frame combine with the grippy silicon strap for a perfect fit with any 509 helmet.

• PC outer lens with anti-scratch coating, and internal anti-fog coating
• Outriggers with Latch system for quick lens change
• 45mm strap with silicone to hold strap in place
• Tear off posts
• Removable nose piece
