Clear material, made with super transparent PVC provides maximum visibility and prevents fog from covering your sight. Durable and practical. Wrap-around face shield covers your face maximally by covering area from top of the eyebrow to chin. Fixed spectacle frames can be worn with thin frame glasses. Covers from mid forehead all the way down to below the chin area.
