Tactical eye protection needs to provide safety, comfort, reliability and performance, which is why Wiley X Eyewear is proud to introduce the Wiley X PT-3. One feature is the "Take-Flight" nose bridge, fashioned with durable rubber and set on a wire core to easily adjust to the bridge of any nose. These glasses also come with an adjustable leash cord and Wiley X's T-Peg Docking elastic strap to fasten the PT-3 firmly across the temples and comes pre-packaged in a durable case with Velcro loops on the back perfect for attaching the Wiley X PT-3 to a belt, backpack or handlebar for easy access. Another feature of the PT-3 is its prescription insert plug-in that's fully interchangeable with Wiley X's new Nerve goggle, to provide incredible versatility to match any tactical or sporting application. Meeting military standards for spectacles as well as requirements for high velocity impact standards, the Wiley X PT-3 features an eight base wraparound and comes in two package options, the PT-3SC with smoke and clear lenses or smoke, or the PT-3SCL clear and light rust lenses.
