Airfoil polarized Rx able Floating Goggles with Interchangeable Lenses The Airfoil 7600 series, one of our best selling polarized goggles, is reminiscent of a bygone era. The frame is lined with dense polyurethane foam providing an airtight seal for maximum protection from wind and dust. The comfort flex frame is vented to keep lenses from fogging. Each 7600 model comes with its two lenses: a set of polarized neutral gray lenses and a set of non-polarized blue lenses. The Airfoil 7600 series can be converted to prescription lenses. By using the extra set of lenses as a template, an optometrist can place your prescription into the frames of these goggles. Each goggle comes with a nylon case with a handy belt clip and a microfiber cleaning cloth. The Airfoil goggle also floats.
