One sunglasses lens color won't fit all fishing conditions. Copper and amber tints heighten contrast for inshore anglers; gray performs best for offshore blue-water fishing. So Costa created its Skimmer sunglasses with interchangeable lenses. The lightweight, semi-rimless frames are made of co-molded nylon with flexible integral hinges and come in black and tortoise. The polarized polycarbonate lenses come in gray, copper and amber tints. Prices range from $139 to $189 depending on lens choices. Visit www.costadelmar.com.
