The ESS Eye Pro Crossbow Suppressor Kit is an innovative frame and interchangeable lens system that accommodates use with full ear cup ear protection and comm link setups. The ultra-thin Crossbow Tri-Tech Fit stems feature Z-Bend Geometry, which is optimized for comfort when worn under full ear cups. The frames house 2.4 mm high-impact polycarbonate lenses, which offer full peripheral vision for a large, distortion-free field of view, as well as full UVA and UVB sun protection. They are also coated with a ClearZone anti-fog treatment and FlowCoat scratch-resistant treatment for maximum durability. The non-slip rubber nose pad and DedBolt Lens Lock keep the lenses secure within the frame and the glasses snug on your face. Engineered for pressure-free wear and ultimate tactical utility, these are high-tech glasses you can count on.
