Underhood having combined skirt and release means

Claim 1

Cleanroom garment for protecting an environment from contamination from the wearer's head and face, characterized by: (a) a bonnet part constructed to cover most of the user's scalp hair and fit loosely, and having a lower open end fitted to encircle the wearer's scalp in the manner of a brim hat; (b) the bonnet part being constructed of fabric which is selected to have a maximum degree of breathability of humid air, and which has a porosity which does not exceed that required to block cleanroom contaminants from escaping from the wearer's body through the bonnet part; (c) a face skirt part attached to the lower bonnet part and substantially encircling the wearer's head, the lower open end of the bonnet part and said attachment to the lower open end of the bonnet part being effected so as to seal the lower open end of the bonnet part against the face skirt part; (d) the face skirt part extending from the lower open end of the bonnet part to a location below the wearer's head, thereby permitting the face skirt part to be tucked beneath a shirt garment worn by the user; (e) the face skirt part being constructed of fabric having an elastic property, so that the face skirt conformally fits against the wearer's scalp at the location of the attachment of the face skirt part to the lower open end of the bonnet part; (f) the encirclement of the face skirt part around the wearer's head discontinuing below the attachment to the lower open end of the bonnet; (g) the face skirt part being constructed of fabric which is selected to have an ability to wick moisture from the user's skin, while retaining breathability of humid air, and which has a porosity which does not exceed that required to block cleanroom contaminants from escaping from the wearer's body through the face skirt part; (h) a face mask, the face mask being constructed of fabric which is selected to have an ability to wick moisture from the user's skin, while retaining breathability of humid air, and which has a porosity which does not exceed that required to block cleanroom contaminants from escaping from the wearer's body through the face mask; (i) the face mask being constructed of substantially non-elastic fabric which is selected to have an ability to wick moisture from the user's skin, while retaining breathability of humid air, and which has a porosity which does not exceed that required to block cleanroom contaminants from escaping from the wearer's body through the face skirt part; and (j) attachments for attaching the face mask to the face skirt part, including at least one adjustable attachment, the attachments located on the face skirt at positions such that the wearer, upon securing the face mask across the face, will position the face mask properly by securing the face mask for comfort; (k) the cleanroom garment providing an elastic bias of the face mask across the wearer's face, the elastic bias of the face skirt part providing a desired tension across the face mask which is adjustably established by said securing the face mask across the face by means of said adjustable attachment, the elastic bias being effected without deformation of the face mask around the wearer's face, although the elastic property permits the face skirt to stretch during movement of the wearer.
