Flowing Titanium with a sporty edge. The Porsche Design P´8917 sunglasses stand out from the other models in the collection with their slim and nearly frameless design. The look and finish of these men's sunglasses are unmistakably Flowing Titanium: exclusive titanium meets highly functional spring hinges and a unique temple design. Inspired by the silhouette of the Porsche 911, the 3D design of the temples creates a rolling landscape of mesmerizing light and shadow.
