Extremely practical technology, stunning appearance: The revolutionary, maintenance-free Ball Tec ball-and-socket hinge on the Porsche Design P'8913 sunglasses perfectly encapsulates the Porsche Design philosophy: maximum function, timeless form. Slender temples crafted in pure titanium put the emphasis on the innovative ball joint whilst being a contrast to the striking front made of ultra-lightweight RXP® high-performance polyamide. The double bridge in a contrasting shade gives this timeless pantone frame a highly individual, modern, and extremely exclusive look. The unique style, exceptionally precise production, and unbeatable comfort set these glasses apart—a masterpiece for living. Available in colorway D (grey/green pol. XTR blue gradient) with innovative Vision Drive® Polarized XTR lens technology, and in colorway C (brown/grey pol.) with Vision Drive® Polarized XTR lenses.
