It's clear that the inspiration for the Maui Jim Waterman Polarized Sunglasses is rooted in the long history and tradition that surrounds those who share a passion of water and watersports for work or for play. The durable nylon frames are designed to handle choppy waters and have a rubber inlay for additional support, while the polycarbonate lenses are built tough with scratch and impact resistance when fishing rods are swinging wildly on the deck. Equipped with Maui Jim's color infused lens technology, PolarizedPlus2, the Watermans eliminate 99. 9% of harsh glares, 100% of harmful UV rays, and boost the colors around you to give you a whole new way to look at the world. The built in strap ensures that these shades don't go overboard when the wind really picks up and your vessel gets moving at a lightning fast clip. A vast eight base curvature delivers a wide range of view to see everything on the water, and the included case keeps your sunnies safely stored until the next voyage.
