Abstract: A disposable and anatomically reversible undergarment shield for removable attachment to the inside of underpants. The undergarment shield is shaped like an hourglass and has a thick portion which is reversible between a front side and a rear side, depending upon whether the wearer is a girl or a body. Words, colors, or other appropriate symbols are placed upon the end borders of the shield to indicate which side forms the front for a girl and likewise for a body. For more rapid and effective absorption, a generally Y-shaped trough is formed in the thick side of the shield. Gathers at the periphery of the crotch region ensure a close fit, thereby preventing leaks. Adhesive strips are used to attach the shield to the undergarment.
