Brass Knuckle Spectrum (BKFLEX-4040N) brings together flexible comfort and peak anti-fog protection for safety eyewear wearers never want to take off. Spectrum helps prevent lens fogging with BK-Anti-Fog lens protection. It permanently bonds to the lens and will not wear or wash off. Its anti-fog protection exceeds European EN 166/168. For comfort, Spectrum features bowed, super-flex rubber temples that ratchet for custom fit. They touch the wearer only behind the ears, eliminating all pressure points. These ratcheting flexible temples offer a true face-hugging design that inspires compliance. Capping it off, the second-generation PivotEase nosepiece slides up and down and pivots on a hinge for added secure fit. Spectrum brings all this to bear while also retaining its anti-scratch, anti-static, and UV protection properties. Each lens color in the family sports a unique, corresponding temple color.
