Optically clear and disposable, this face shield protects the entire face without obscuring the wearer's vision. The soft foam headrest lays across the forehead for comfort, and holds the 100% PET (polyethylene terephthalate) shield off the user's face to allow room for eyewear and masks. The stretchable polyester strap adjusts to most head sizes, creating a snug and comfortable fit. This full length face shield is intended for use against liquids and particles, however it is not approved for impact or open flames or sparks.
