Our face shields are made from durable polycarbonate plastic and are optically clear for ease of use. The strap that fits around your head is connected with an elastic tie and has three adjustment positions to ensure that this face shield will fit any person. The medical grade foam on the inside makes this face shield very comfortable to wear and the offset from your forehead allows for venting of any excess moisture from breathing. As it has been shown that Covid-19 can enter through the eyes, our complete coverage will aid in protecting your whole face. The size of the face shield is 12-3/8″ wide x 9″ tall. The plastic strap is 22″ long and 1-1/4″ tall. The foam is 1″ medical grade foam. Each face shield is packaged and sealed separately.
