An improved head cover for insulating a head of a garment press apparatus is disclosed having an inner layer of heat-resistant material configured to directly and contiguously cover a non-pressing upper surface of the head. An outer fabric covering of heat-resistant material is secured to and covers the inner layer to form a single piece. The head cover contains a cutout portion and at least one slot, for accommodating a portion of a supporting mechanism attached to the head and a portion of a steam inlet conduit, respectively. First and second portions of the head cover are detachable from one another for easy installation of the head cover on a variety of heads.
