What happens if you're in the field, working beneath a vehicle, and a 1.1 lb. projectile impacts your wraparound sunglasses from a 50-inch height? If you're wearing Gargoyles Vortex sunglasses, nothing. Our wrap around sunglasses for men take the hit. You're wearing very purposefully designed, highly tactical protection. Vortex meets the military specification MIL-PRF-32432(GL) for high velocity and high mass impact. They also exceed all ANSI Z87.1+ protection specifications, including, but not limited to, impressive optical clarity. And thanks to the TR90-NZZ frames, even the Gargoyles G-Loc hinges are 11 times stronger than regular TR90. The browbar and temples of our square sunglasses feature co-injected rubber, which provides comfort, stability, flexibility and grip. With anti-reflective and Tri Tech oleophobic treatments, the lenses control harsh light and are both water and smudge resistant. Vortex offers serious strength, dependability, and protection for whatever comes your way.
