Rudy Project Exception Tactical The Rudy Project Exception™ offers a vast array of features all packed into a stylish cutting-edge design. The Exception™ is truly a design masterpiece that has incorporated all of our major technologies in one model - including the option to add Rx-ability using our patented optical inserts. RP Optics polycarbonate lenses can be put directly into the frame or ingeniously added to our flip-up mechanism that attaches to the frame - offering two vastly different functionalities and appearances. The Exception™ incorporates Quick Change™ interchangeable lens technology, adjustable Ergonose™ nose pads (to eliminate fogging) and adjustable Kynetium™ temples equipped with our T-Lock™ system for a customized, total comfort fit every time. Advanced lightweight Grilamid™ TR 90 frame material and geometric wrap technology means you won't even know you have them on!
