Nice system with great versatility - ESS Interchangeable Component Eyeshield (ICE) 2.4 Safety Sunglasses

You get great versatility from this US Made product. Changing lenses is simple and straightforward. The ability to add the prescription insert only adds to the usability of the item. From a durability standpoint, the temples are flexible, and it seems they would be hard to break. As for the lenses, given the ASTM rating for impact they are great shooting glasses (high contrast yellow lens) and the clear lens works well for night riding on your bike, motorbike or as eyeguards for racquet sports like squash. Finally, the semi-hard shell case keeps everything neatly tucked away and has held up well.
