This powerful ANSI Z87.1+ protection weighs significantly less than one ounce and the rimless lenses are manufactured with our BK-Anti-Fog protection. Bowed, super-flex temples touch the wearer only behind the ears, eliminating all pressure points while delivering the optimal fit. The ratcheting flexible temples offer a true face-hugging design that inspires compliance. PivotEase™ nosepiece slides up and down and pivots on a hinge.
