The P’8678 sunglasses are a new interpretation of their predecessor, the P’8478 model, and are also made of pure titanium. They are lightweight and therefore comfortable to wear. The distinctive shape of the lenses is one of the sunglasses’ hallmarks which has been retained but updated for this model. The latest generation of interchangeable lens technology used by the manufacturer ensures that the lenses can quickly and easily be exchanged, thanks to a new locking mechanism.
