JT lenses pass the American ASTM standard and the European CE 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
• Will fit JT Proflex, JT Flex-8 and JT Proshield goggles
• Dual-pane Spectra Thermal Lens for reduced fogging
