The all new 509 anti-fog fan, stops fog dead in it’s tracks. If you are a heavy sweater or just want an extra level of fog stopping protection, the 509 anti-fog fan is for you. This is a removable fan module that installs directly into your existing pair of 509 goggles. In fact this 509 version was specifically re-engineered to work with both 509 Sinister & Aviator goggles. No other fan product on the market is directly compatible with both 509 goggle models. In addition, it’s compatible with virtually every other goggle brand on the market.

ALL NEW FOR 2010! The all new Aviator snow goggle from 509 features a design inspired by the face shield of a jet fighter pilot. This unique styling brought from the aviation industry, provides not only a futuristic appearance, but more importantly performs even better in even the harshest winter conditions.

509 Sinister snowmobile goggles were designed from the ground up to be, what 509 feels, is the first 'true' snowmobile specific goggle. Every design element and every feature was specifically engineered to tailor specifically for a snowmobiler's requirements. There is a HUGE difference between a ski goggle and a 509 snowmobile specific goggle. So often we see sledders frustrated with their poorly performing goggles and as no coincidence, they are always a ski or snowboard brand.

Brand new this year, is the highly anticipated Sinister Black Ops goggle. The first and only 509 goggle that comes standard with a polarized smoke lens. This special edition model features a new matte black frame color, 509 metal badge on the strap, and of course a smoke tint polarized lens.

509 and Chris Burandt have teamed up to create the Burandt Backcountry signature series goggle. Featuring a design inspired by Burandt's backcountry style of riding. This goggle also comes standard with Burandt's favorite lens, a plain yellow tint. Finally this signature series goggle features an all new 2" wide strap for extra grip.

All 509 lenses include four foam lined ventilation ports, 100% UV blocking, anti fog & anti scratch coating, and shatter proof material. All lenses are replaceable and interchangeable. They are available in many different colors for a variety of weather conditions. 

These are a highly recommended lens! Setting the industry standard once again for snowmobile optics, 509 has released their all new polarized snow lenses. Polarized lenses provide the very best clarity, definition, and glare reduction in snow environments. The benefit of polarized is they literally work in every imaginable snow condition. From low visibility foggy conditions to bright sunny days, there is no better lens. These are truly one lens that does everything. No longer do you need to carry multiple lens tints for varying weather conditions.
