Thermal Lens Mask Jt Spectra Smoke Goggle

JT lenses pass the American ASTM standard and the European CE standard, but it doesn’t stop there. JT shoots them, stomps them, hits them with 1/4 inch steel balls at 400 fps, stretches them and lets the dog chew them. And it proves one thing – JT lenses meet an even higher standard – the JT standard. With a thermal coated anti-fog inner lens that can be cleaned with a JT Micro Fiber Cloth, the standard has been raised even higher to include pure optical style.
