The Suncloud Hundo Sunglasses have a squared frame made of injection molded nylon, which gives the shades its ultra-durable and flexible exterior. The lenses, also injection molded, are made from polycarbonate, a lightweight, impact resistant material. They offer polarization to eliminate distortion of color and complete UV protection as well. Pop these sunglasses on any time, whether you are on your way to work or on your way home from a day at the beach.
