Spy pushes the boundaries of technology and style in these Hielo sunglasses. The rectangular frames are crafted in hypoallergenic propionate—a lightweight nylon that's still plenty strong for your active lifestyle. A wraparound rim design provides impressive protection at the periphery. The robust temples curve inward for stability behind the ears, and attach to the rims with sturdy 8MM hinges. The Spy cross logo on the temple finishes these shades a sporty pop. Created by athletes for athletes, these Spy sunglasses are ready for every outdoor adventure.
