When you try on the Crossbow®, you'll discover it's unlike any other ballistic eyeshield. Experience the Tri-Tech Fit™ frame that achieves an amazing universal fit with max comfort and zero pressure points. Then notice the lenses. They won't fog. That's thanks to groundbreaking ClearZone™ FlowCoat technology, engineered to eliminate fog inside and prevent scratches outside. As you stare down your objective through distortion-free ESSOPTICS™, you'll see just how optically precise vision can be. When you're ready to switch tints, the innovative DedBolt™ Lens Lock pivots up for easy release, then clamps down for rock-solid retention under impact. ENGAGE. ADAPT. EXCEL. As part of the ESS Cross-Series ™ eyeshield platform, all Crossbow® components are compatible and fully interchangeable with the ESS Crosshair™ and ESS Suppressor ™. For example, you can upgrade a Crosshair™ to premium Crossbow® anti-fog lenses—including ANSI-rated Polarized—or adapt for hearing protection use with the ultra-thin Suppressor™ frame. It's from ESS, so of course the Crossbow is compliant with U.S. Federal OSHA, ANSI Z87.1?2015, CE EN 166 and U.S. MIL-PRF-32432A. Form, Fit, Function...Perfected.
