The 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. The Aviator is engineered using a 'rimless' frame design. This sleek design minimizes the amount of goggle frame in your field of vision. By reducing the thickness of the frame, we are able to use a much larger spherical lens without increasing the overall footprint of the goggle. This maximizes the goggles lens to frame size ratio, providing industry leading peripheral vision. The problem with traditional goggles is they tend to restrict your vision. We addressed this concern head on and focused on designing a snowmobile specific goggle around the absolute largest lens possible. The result is an unprecedented clear view, never before provided in a snow goggle. This no fog, anti scratch dual pane lens features 7 vent ports and blocks 100% of harmful UV rays. The 509 Aviator is a high end goggle built with only the best materials and craftsmanship. We spared no expense and cut no corners in the design and development of this goggle. The attention to detail is second to none. Aside from the unique rimless design, and oversized spherical lens, we also focused on improving the strap. The 509 Aviator goggle features a 2" wide strap with triple silicon lining that provides even greater helmet grip. Instead of a traditional sewn strap design, we developed a "509" chrome strap emblem attached with a real leather backing. 509 Aviators also come standard with our famous removable nosemask, which keep you comfortable even in the coldest conditions. They also come standard with oversized triple layer face foam.
