Oakley's new Crossrange sunglasses were designed for those on the move. Whether it's for active use or simply exploring the city, the sunglasses were designed from the ground up to transform into a frame that is perfect for things like running or cycling and then can be changed up for everything else. What they've done is created a modular design that has easy to swap grippy earstems and nose pieces for sport and and an opposite of lower profile pieces for everyday use.
