The protective faceshield covers forehead and chin.
It can be worn comfortably over masks or glasses, without obstructing eyesight.
The protective faceshield visors are supplied unassembled, however the operation is very simple, simply insert the visor into the appropriate slot in the front headband, and wear it. There is no need to glue it or anything else as the pressure exerted by the bow keeps the transparent sheet fixed and stable.
They can be cleaned with a soft cloth or with a mild soap or detergent and water.
