Boasting the same great features as the standard Vise®, The XL version is the first pair of (you guessed it) EXTRA-LARGE Heat Wave frames specifically designed for the ones with larger than average heads. We took the time-tested design of the Vise® and added an extra 10mm in width and jacked up the ride height to 5mm to provide Godzilla-like, larger than life comfort and coverage. About The Vise® Z87: features an all TR90 construction and 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. Meets Z.87 Requirements, and Z87+ with add on Side Shields Our lenses are injection molded from thick 1.9mm shatter-resistant polycarbonate that is built to withstand Z87 Mass Impact Standards. Add on optional side shields for additional lateral protection to meet Z87+ standards Each pair of Vise® Z87 is boldly marked Z87 on the frame, arm and lens. Disclaimer: Removing arms, and or changing configuration in any way voids Z87 compliance.
