Abstract
Abstract A disposable absorbent article, such as a disposable diaper, having barrier leg cuffs. The barrier leg cuffs have a distal edge which is spaced from the proximal edge so as to provide a barrier against leakage. The barrier leg cuff has a portion affixed to the diaper so that the spacing between the barrier leg cuffs is increased in selected portions to reduce irritation of the genetalia and to provide a larger area to receive bodily discharges.
