The S22 offers a 15% smaller lens than the S21 Series and our exclusive spring-hinge temple design. Both styles offer ultimate protection, great orbital seal and and a slim and lightweight design.
High velocity impact safety glass test method is performed by shooting a 1/4" steel ball at a speed of 150 feet per second aimed at the center of the lens.
