The Crosshair features interchangeable 2.4mm polycarbonate high-impact lens that provide 100% UVA/UVB protection. ToughZone lens coating for maximum scratch resistance. The ESS Crosshair exceeds ANSI Z87.1 optical standards and U.S. Military impact requirements while providing all-day comfort and a universal fit. This entry-level eyeshield goes well beyond the basic necessities of eye protection: with a baseline of advanced performance and superb adaptability, the Crosshair benefits from complete compatibility with the ESS Cross-Series eyeshield platform. As part of the ESS Cross-Series, the Crosshair can be upgraded at any time with premium anti-fog Crossbow lenses, including the high-impact Polarized Gray option. It can also be adapted for use under hearing pro and comms gear with ESS' ultra-thin Suppressor frames. With the Crosshair and Cross-Series, ESS has bridged the gap between price and premium performance. Now, more than ever, your eye pro kit can match your mission requirements, and your budget. The Crosshair ONE kit includes the Black Tri-Tech Fit Crosshair frame with a Clear lens, Micro-fiber pouch, ESS sticker and instruction booklet.
