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 2X Kit includes Two fully assembled black framed eyeshields. One is the Suppressor frame with the Hi-Def Copper lens and the other is the standard Crossbow frame with the clear lens. Also included is the zippered hard case, micro fiber pouch, snap-on elastic retention strap, ESS U.S. Flag sticker and instruction booklet.
