Designed specifically for ear cup hearing protection and communication devices, the ESS Crossbow & Crossbow Suppressor Frames with Clear & Smoke Gray Lens is at the forefront of spectacle technology. Featuring Z-Bend Geometry, the frame's ultra-thin temple arms minimize the impact on the padded seal of ear cups, reducing noise and maintaining protection. The Suppressor frame retains compatibility with all Crossbow lenses, featuring 2.4mm Polycarbonate lenses with ESSOPTICS and ClearZone FlowCoat technology for distortion-free vision, anti-fog interiors, and scratch-resistant exteriors. The DedBolt Lens Lock provides an added level of security with its quick lens interchangeability and supreme retention under impact.
