Abstract: A protective shield features a single-piece transparent dome or shell having a rear opening through which facial and cranial regions of a user's head are received, thereby providing improved coverage over conventional face shields that cover the face only. Inward protrusions at a transitional region between the facial and cranial portions of the shield rest against the forehead to offset the facial portion of the shield forwardly of the user's face to allow airflow, optionally introduced from an external fan via an airflow channel integrally formed in the cranial portion. A flexible connector clip has a J-shaped profile for engaging an out-turned flange around the boundary of the shield s rear opening, to enable clipped connection of a bib or shroud. Support protrusions in an underside of the cranial portion maintain airspace above the head, which is further optimized by a rearwardly sloped incline of the cranial portion.
