The Oakley Latch Grid Prizm is a creative collaboration from the world of skateboarding, this design inspired by influential athletes is shaped with a classic keyhole bridge and the curves of rounded lens orbitals, and Oakley engineered it with the convenience of an interior kick-up feature that lets you clip it to your shirt. Each frame is nuanced with manufacturing information on the temple, and a perforated grid highlights the hinge mechanism that lets you latch these sunglasses to your shirt.
