These Longline Sailfin polarized sunglasses are a necessity for those that like to spend days on the lake fishing on the open water. The 1.1 mm polarized lenses will reduce the glare from the water, so that you can focus on relaxing in the boat instead of worrying about the intense light. The reduced glare will also allow you to see in clear waters more easily. You are protected from the sides too, because the wide temple design blocks most light in your peripheral vision. The frame is white with gray lenses that provide 100 percent UV protection. Measures 48mm tall, 148mm long, and 127mm wide.
