If you want a secure fit, precision from Ironman provides you with wrap-around sunglasses designed to stay put plus the added security of an adjustable strap. In addition, the rubberized plastic body enhances flexibility and slip resistance. These glasses will stay on for just about any activity from jogging to hang gliding. They're great motorcycle glasses too. The polarized lenses reduce reflected glare from wet or shiny surfaces so you get excellent visibility when you are on the water, on the snow, or facing any condition where reflected light is a problem. Precision sunglasses also block 100 percent of UV rays, and their lenses are scratch and impact resistant, which means clear viewing minus the annoying marring that can occur from everyday wear and tear. The black and red color design adds to the appeal of these sunglasses that measure up for good looks and functionality.
