Old-school style with modern details – the new Heritage collection pays homage to the legendary roots of Porsche while drawing on the latest technologies. Porsche Design P'8678 sunglasses present an exclusive reinterpretation of the iconic P'8478 from 1978 – rendered in high-tech titanium. The classic teardrop-shaped lenses feature an intelligent release mechanism for a quick and easy exchange that allows the wearer to exchange lenses quickly and easily to adapt to different light conditions. Robust, impact- and scratch-resistant polycarbonate lenses. History in its most innovative form.
