JT Spectra / JT Proflex Flex Thermal Lens - Hi-Def

JT lenses pass the American ASTM standard and the European EC Standard, but testing doesn't stop there. JT shoots them, stomps them, hits them with 1/4 inch steel balls at 400 fps, runs over them, and lets the dog chew them. And that proves one thing - JT lenses meet an even higher standard - the JT Standard. With a fog-resistant coated thermal inner lens that can be cleaned with a JT micro fiber cloth, the standard has been lifted even higher to include pure optical style. Features: Replacement thermal lenses for the Spectra series of JT goggles ASTM UV A & UV B protection Dual pane construction to prevent fogging Reduced glare Color contrast and clarity For use in partial cloudy and sunny condition
