509 Sinister XL7 Fuzion Flow Goggle
Built for riders who demand maximum visibility and comfort, the 509 Sinister XL7 Fuzion Flow Goggle is designed to pair perfectly with snowmobile, snowmachine, and off-road helmets—especially in larger 2X+ shell sizes. Featuring a 20% increase in face foam, these XL-sized snow goggles deliver an improved seal, all-day comfort, and better compatibility for riders who wear glasses (OTG).

Experience the clarity of Fuzion Lens Technology, combining the durability of a single pane with the fog-fighting power of a dual-pane design. Cylindrical no-fog lenses expand your field of view, while the shuttered frame venting system allows riders to tune airflow for changing weather and riding conditions.

Whether you're carving trails, deep-snow boondocking, or cruising the mountain on your snowmobile or sled, these premium riding goggles deliver dependable performance in low light, bright sun, or fast-shifting conditions.
