Affordable and premium: two words that haven’t existed together in goggles…until now. The 509 Kingpin Goggle puts performance within reach by combining a quick-change lens system along with high-end anti-fog and anti-scratch dual pane lens technology. To change the lens, simply rotate the left and right mounts 90-degrees. It’s that easy. Like all 509 goggles, the Kingpin pairs perfectly with 509 helmets for a seamless fit that optimizes performance and comfort.
