The S22 Series offers a single wrap-around lens design with integral side shields and metal alloy temples. The S22 offers a 15% smaller lens than the S21 Series, making it a good safety glass option for women and kids. Constructed with our exclusive spring-hinge temples, this style provides ultimate protection, a great orbital seal, and a slim and lightweight design. The S22 also features a frameless lens design, which provides an unobstructed view. Other features include metal temples and non-slip temple sleeves.
