It's common to stick a sunglass stem into a shirt when they're not needed. It's also common for them to fall out, and potentially take damage when bending over. Oakley's Latch Panel shades have a unique hinge that clips to shirts, keeping them secure on the go. That same mechanism supports the removable side shields, which combine with the Eyeshade-inspired full-rim Prizm lens to provide maximum coverage while enhancing contrast, color, and clarity. The lightweight BiO-Matter frame is made from at least 56% bio-based carbon content. It works with the Unobtainium nosepads and earsocks to keep them securely on the face even during vigorous activity.
