The PISTOL+™ model is an interchangeable dual lens "Combat Eyewear System". The Ballistics and Safety rated lenses provide needed shrapnel fragmentation protection for soldiers' eyes. The lenses are anti-scratch and hard coated, protecting against chemical deterioration from DEET, hydraulic fluids, & petroleum-based fluids such as gasoline, motor oils, and JP8 fuel. A comfortable streamlined fit is further enhanced with our latest development of "Panascopic" tilt and "Telescopic" capable temples. These capabilities permit adjustments for a more perfect fit depending on the soldiers face contours. The complete PISTOL+™ kit includes the frame, two 2.1mm ballistic & safety rated polycarbonate lenses, (clear & grey), a retention cord, and cleaning cloth, all packaged in a semi-hard case. 100% Made in USA
