Skullerz ODIN Anti-Scratch & Enhanced Anti-Fog Safety Glasses feature a durable full-frame design that bends and flexes without breaking. These safety glasses feature tough anti-scratch and anti-fog polycarbonate lenses to protect against impacts and filter 99.9 percent of harmful UVA, UVB and UVC rays. Available in a variety of lenses to suit a range of tasks and light environments. A non-slip rubber nose piece and rubber temples keep the glasses secure and resist sweat. The integrated accessory receptors at each temple also improve airflow when not in use. For added safety, an elastic retainer strap or foam gasket insert (both sold separately) can be attached to the temples.
