Introducing the ALL NEW Sinister MX-5 premium motocross goggle. This ultra high end dirt goggle was born from our best selling snow goggle, the X5. Featuring the same goggle frame, we meticulously customized a dirt specific single pane lens with tear off posts and a sleeker, rigid removable nose mask. We also lined the frame's air ventilation ports with a summer specific higher flow foam material. This foam technology allows maximum air flow while keeping small dirt & dust particles out.

The single pane lens features a chemically bonded anti-fog & anti-scratch coating for maximum performance.

The fixed edge pressure outrigger system makes for a perfect fit & seal with your 509 brand helmet. So long are the days of mix & matching two different brand dirt goggles and helmets. 509 Sinister MX-5 goggles and 509 brand helmets are a combo designed to work in perfection.

The Sinister MX-5 also features our completely re-engineered PHANTOM FRAME TECHNOLOGY. The PHANTOM FRAME was completely redesigned to provide the absolute maximum field of vision in the game. Through advanced engineering we were able to literally hide the frame from your field of view, giving you the maximum visibility possible. The Sinister MX-5 frame is 0.5� taller than our traditional Sinister, giving you a significantly improved field of view. We engineered every angle of the Sinister MX-5 PHANTOM FRAME to slope perfectly to the contours of your face, while minimizing the amount of frame in your field of view. In addition, the frame was designed to fit perfectly inside your 509 helmet.
