Named after the deep blue Bahamian waters where the Bluefin tuna travel north, the Costa Del Mar® Tuna Alley 580P Polarized Sunglasses were made to reveal the magnificent underwater fish highway. These wraparound shades were built with integral hinges, a patented vent system to prevent fogging of the glasses and 100% polarized lenses that protect against all UV rays. Not only are the polarized polycarbonate lenses lightweight and protect against the sun, but they also filter out unwanted glare and reduce eye strain. Don’t miss a thing on your next fishing trip when you wear the Men’s Tuna Alley 580P Polarized Sunglasses.
