Abstract
Abstract The present invention is a diaper or incontinent garment of the usual construction having generally trapezoidal wing-like waist encircling portions at each end with a constricted crotch zone located between them. The waist encircling portions of at least one end, preferably at the rear, have discrete areas containing ventilating apertures. These areas are located between the absorbent pad and the lateral and transverse margins of the diaper. The use of this construction gives ventilation in the pad-free areas to reduce the incidence of diaper rash.
