Minimalist design meets innovative technology: With its new concept called Ball Tec, Porsche Design has created an outstanding hinge solution. An extremely precise and high-tech injection molding process was required to create this new design concept. The revolutionary hinge solution, characterized by a ball joint, harmonizes perfectly with the ultra-lightweight front. The two components in combination with an anatomically pre-fitted temple made from 100% pure Titanium, provide perfect wearing comfort.
