These sunglasses by Locs are all OG business. The frames are thick and solid looking, made of black plastic. They are strong and fit solidly on the face and head. " Retro Future " ? Think Arnold Schwarzenegger in the 90's, but in the Future. Square Frames with layered internal lines, Metal bar and Locs Script on the arms. UV400-rated lenses, these glasses perform the task required of them.
