- Collection:SHEET TITANIUM - A combination of 100% pure titanium and beta-titanium. Cook is Ørgreen's largest frame, characterized by bold lines for equally confident males. The straight top line frames the face effectively in metallic tortoise titanium, a reinterpretation of the tortoise acetate of previous seasons. With additional strokes of hot red, navy, and matte green, the style reflects the diverse visualities of Cook's travels in the Pacific Ocean.
