Our goggles use a dual lens designed specifically for cold weather & high moisture use. Built with 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.
12 Month Lens Replacement Warranty. 509 lenses are covered for 12 months from your date of purchase against any breaks or cracks that are caused by normal usage.
