The Sinister X5 goggles from 509 uses a dual lens designed specifically for cold weather & high moisture use. Featuring complete UV protection, dual lens panes, anti-fog, anti-scratch, and shatter proof. Each lens is uniquely designed with dual view technology. This dual view technology is a new feature we perfected & included on our goggles, so they not only look sharp when in action, but also have the unique functionality of two completely different views depending on if you are the one using the goggles or viewing them from the outside. This encompasses the best of both worlds by providing a functional lens that increases snow definition yet doesn’t have the bland look of a standard tint lens!
The Sinister X5 Max Vent lenses have more than twice the lens vent surface area versus the standard X5 lenses. This includes 6 large top vents and two strategically placed lower vents. These lenses are perfect for riders that need increased airflow for improved anti fog performance.
