Orgreen thinks outside the box when it comes to sunglasses frame design. The Ogreen Quantum collection utilizes a spherical ball hinge, which is hidden between the sunglasses polymide front and titanium temple. This design eliminates extraneous components such as screws and bolts.
Ogreen titanium is the some of the best in the business, they use pure, high grades of titanium. Orgreen's solid titanium frames are thru out the frame, not just in a few tiny spots on the sunglasses frame.
