The ESSￂﾠCrossbow Suppressorￂﾠis the first spectacle frame designed for use with ear cup hearing protection and communications devices. FeaturingￂﾠZ-BendￂﾠGeometry, the frame's ultra-thin temple arms help keep noise out by minimizing the effect on the padded seal of ear cups. The slim temples eliminate the hot spots and pressure points that commonly occur when normal eyewear is worn under ear cups. The Suppressor frame is compatible with all Crossbow lenses. The 2.4mm Polycarbonate lens feature distortion-free ESSOPTICS and ClearZone FlowCoat technology to combat fogging on the inside and scratches on the outside. The frame's DedBolt Lens Lock provides quick lens interchange and rock-solid retention under impact. The Crossbow Suppressor ONE Kit includes the black Crossbow Suppressor frame with interchangeable Hi-Def Copper lens, Micro-fiber pouch, Snap-on elastic retention strap, ESS sticker and Crossbow instruction booklet.
