Edge Kazbek Safety Glasses Silver/Black Frame Silver Mirror Lens

The Kazbek's frame is constructed of a nylon composite material that can be tied into a knot. And while we don't recommend tying yours into a square knot, the flexibility of the frame means you get a comfortable, yet virtually indestructible, pair of safety glasses or sunglasses. The Kazbek is just at home on the water as a pair of fishing sunglasses as it is on the job as safety eyewear. A thermoplastic rubber (TPR) nosepiece offers a comfortable, non-slip fit. And the lenses block 99.9% of UVA, UVB and UVC rays.
