As tough as they look, Rucker glasses are built to withstand whatever comes your way. Military-grade protection and performance in a wearable style. Rucker meets MIL-PRF- 32432(GL) for high velocity and high mass impact. They also exceed all ANSI Z87+1 protection specifications to ensure you are equipped to perform your mission whatever it may be. The teardrop lens shape offers 180-degree wrap protection. Lens vents promote better airflow to prevent fogging, and a built-in brow bar helps keep sweat out of our eyes so you can keep your eye on the target at all times. TR90-NZZ frames and the Gargoyles G-Loc hinges are 11 times stronger than industry standard TR90. Rucker's temples are flexible and thin for maximum comfort under ear pro or helmets. Individually adjustable nose pads ensure a custom fit and are ribbed to help airflow and provide extra grip. With anti-reflective and Tri-Tech oleophobic treatments on the lenses, you'll notice light control in any environment and ease of cleaning. Technology and design at its finest.
