Compact and low-profile, the StingerHawk Eyewear System is a wrap-around ballistic spectacle with interchangeable lenses. Its design is sleek and hard-working, exceeding ANSI Z87.1 and U.S. military requirements for ballistic impact (MIL-PRF-31013. clause 188.8.131.52 and MIL-DTL_34511, clause 3.5.10). With flawless optics and a range of tints to suit your mission, StingerHawk lenses are Ocumax flow-coated for powerful anti-scratch protection on the outside and superior anti-fog on the inside. The lenses are also chemical resistant and 100% UV-protective to perform under any circumstance.
