A surgical garment includes a head gear apparatus for supporting a face shield and shroud. The head gear apparatus includes a helmet that supports a fan assembly, and that defines forward and rear ventilation passageways. The helmet includes a chin bar that defines a centrally located slot, and an upper ledge. The upper edge of the face shield contacts the upper ledge, while the lower edge of the shield includes a tab that extends through the slot. The chin bar and face shield include a plurality of magnetic elements that magnetically connect the lower edge of the face shield to the chin bar. The helmet is suspended from a strap assembly that is carried directly on the head of the wearer. The strap assembly includes an adjustable occipital support that bears against the occiput of the wearer. The face shield can include a plurality of film layers that can be removed when soiled. The fan assembly includes an inlet opening and the shroud includes a filter assembly that is sized to overlay the inlet opening and a portion of the helmet surrounding the inlet opening.
