For riders who work hard in the backcountry, we put every anti-fog weapon we’ve got in the revolutionary new 509 Aviator 2.0 Fuzion Flow Goggle. With the optical clarity of a toric lens shape and 5MAG magnetic lens system, the Aviator 2.0 is already a first in powersports. But what sets the Fuzion Flow model apart is industry-first lens technology that fuses Super Anti-Fog inner and outer lenses into one optically clear view, then adds high-flow venting to eliminate fogging.
