Heat Wave Vise Z87 Sunglasses Black Frame: Galaxy Lens Hardhats they also feature reflective bandsThe Vise Z87 features an all TR90 construction. It tightly holds form and function together, as the Vise Z87 meets ANSI Z. 87 mass impact requirements (and Z87+ with add on side shields) featuring 1. 9mm thick lenses to aid in protection against basic impacts and flying debris, which enables the Vise to transcend just that of a regular pair of sunglasses.
