Shown is the Tortoise Shell model ($229), but there are three other colors to choose from: Olive Tortoise, Blue/Black Tortoise, and Black/Grey Tortoise. The Road Trip’s feature Maui Jim’s MauiPure lenses, which is an inject-molded lens (i.e. plastic) that is one third the weight of standard glass, but offers clarity almost as clear as glass. So it’s kinda the best of all worlds. You get the impact resistance and weight-savings of polycarbonate lenses, but the scratch-resistance and clarity is right up there with glass. The glass is also naturally scratch resistant and MauiPure polycarbonate lenses perform better and longer with the added durability of Maui Jim's optically correct Clearshell technology that's applied to the front and back of the lens. On top of that, with every pair of Maui Jims you’ll find the company's patented, color-infused lens technology that wipes out 99.9-percent of glare, 100-percent of harmful UV rays, and boosts color via specially designed lens treatments. So your view is clearer, with crisper contrast and amazing brilliance.
