An oleophobic treatment of the lenses provides liquid and other chemical protection and added scratch resistance, while an anti-reflective coating on the inside of the lenses minimizes distracting reflections. | Durable Comfort Padded low profile temples integrate smoothly under helmets, communication headsets and over the ear hearing protection. Coated stainless steel pins provide simple but dependable hinge functionality and rubber nose and temple pads are overmolded to the frame for durability and comfort. |
