Abstract: A variable sized diaper, which is reusable, is disclosed. The diaper inlcudes an outer liquid impermeable panel having a generally hourglass configuration. The outer panel is sealedly connected about its perimeter to a corresponding inner panel having a substantially identical outer perimeter. The inner panel includes a fluid absorbent core, longitudinally positioned along the length of the diaper which is circumscribed by a plurality of side panels and waist panels which are constructed of liquid impermeable fabric. A conjunction of the inner panel and the outer panel defines a liquid permeable absorbent core which is substantially surrounded by a fluid impermeable hollow pocket or sack which extends about the entire circumference of the absorbent core. A "V"-shaped pile attachment strip is positioned on the frontmost regions of the diaper and is adapted to connect with a pair of hook fasteners one of which is positioned on each of the two wing-like portions of the rear portion of the diaper.
