The frames are made of rugged co-injected molded nylon, with sturdy integral hinges. The hypoallergenic rubberized interior lining and nose pads keep the sunglasses comfortably in place, even in wet conditions.
Cortez frame colors include blackout, tortoise, shiny black, Realtree Xtra camo, crystal bronze, and white with a blue Costa logo.
Like all Costa sunglasses, the Cortez can be customized in a full array of patented color-enhancing polarized 580 lenses. These lenses selectively filter out harsh yellow and harmful high-energy ultraviolet blue light. They also enhance reds, blues and greens, and produce better contrast and definition while reducing glare and eye fatigue.
Costa’s 580 lenses are available in either glass or impact-resistant polycarbonate. Lens color options include gray, copper, amber, sunrise, blue mirror, green mirror and silver mirror. Cortez is also available in customized Rx sun lenses.
