Introducing the very first Mach Gs with Flamingo Eye Technology, which gives you high definition contrast even when the sun isnrsquot shining directly into your eyes. This allows you to see the root that jumps up at you on the trail, or your golf ball on the rough. The Mach Gs are a classic aviator style made to give you the speed if you feel the need. Plus, this smooth, sleek frame means no unsightly imprints on your nose from those weird nose pads on traditional metal aviator frames. Of course, all goodr sunglasses are made with super-lightweight plastic with a no-slip grip so you can run, dance or lounge without bouncing or slipping.
