Abstract

A disposable pant-like garment for absorbing human discharge is provided, and comprises an absorbent assembly comprising a liquid-impervious outer cover, a liquid-pervious liner, and an absorbent medium therebetween. The absorbent assembly also has generally opposite side edges and generally opposite end edges. A pair of stretchable side panels are joined to each one of the side edges to form with the absorbent assembly a waist opening and a pair of leg openings. A gathering means is joined along at least a portion of each leg opening for gathering that portion. The stretchable side panels provide generally inwardly directed force vectors against a wearer to maintain the garment snugly against the wearer'"'"'s body and the absorbent assembly snugly in place against the crotch area both before and after a discharge.
