"What Our Gearhead® Experts Are Saying:""I wore Salina 580P Sunglasses on a stretch of cloudy stream fishing days and the Copper Silver Mirror lens handled the changing light better than I expected. The Bio-Resin frame felt light enough that I forgot I had them on by the afternoon.""Tropical sun and sandy afternoons call for a frame built for exactly that kind of easy, sun soaked day, and Salina 580P Sunglasses deliver it without overthinking the look. Seaworthy interior sculpting on the Bio-Resin™ frame keeps things comfortable whether the plan is a beach walk or an afternoon on the water. 580P polarized polycarbonate lenses in Copper Silver Mirror handle a range of light conditions, making them just as useful for sight fishing on a cloudy day as for everyday wear in bright sun. A C-Wall coating resists scratches and repels water, oil, and sweat, keeping the frame easy to clean no matter where the day leads."
