CROSSBOW is a ballistic eye shield that has been supplied to 300,000 units per year as standard equipment for the U.S. Navy Seals and Marine Corps Designed for comfort and safety, Tri-Tech Fit technology is built to fit a wide range of face types. Using a 2.4mm ballistic lens (high impact polycarbonate lens), the ClearZoneFlowCoat treatment provides anti-fog treatment on the inside of the lens, and the exterior of the lens is scratch-resistant. And thanks to the high technology of ESS Optics, the distortion-free vision will not cause any stress to the user. The DEDBOLT LENS LOCK System also prevents the lens from getting on or off when an impact is impact, allowing for quick lens changes.
