XL330MIXSemi rimless shades are great for sports and outdoor activities, and these nice sunglasses by X Loop are made to be tough and able to stand up to rough use. The frame is made of plastic and molded to fit tight so athletic men don't have to worry about their glasses flying off when they play. The arms are thin and come off the temples and feature rubberized earpieces for better grip. The lenses are strong and dark with a padded nose piece.
