When you need total facial splash protection, choose the Coverall« face shield. The face shield's wrap-around design provides the wearer with great peripheral vision while acting as a protective shield against non-hazardous liquid splash and light particles in a Lab or Controlled Environment. The face shield is not ANSI Z87 rated for eye protection. You can wear the lightweight shield comfortably for long periods and it fits easily over prescription glasses or protective eyewear. A double-sided anti-fog coating reduces the possibility of fogging in high humidity environments. For safe working conditions, the face shield is low distorting and 100% optically clear while a soft polyurethane foam headband securely positions the device on the wearer.
