Abstract

An adult brief garment for use in controlling incontinence is provided. The brief has a chassis which includes a front portion, back portion and an interposed crotch portion. The chassis consists of a fluid-impervious, cloth-like laminate along the central region of the chassis and hydrophobic, cloth-like, nonwoven side panels at each side of the central region. An liquid absorbent core is positioned over the central region. Plural fastening tapes are applied to the side panels at the back portion of the chassis. The front portion of the chassis includes soft, flexible landing zones for releasable receipt of the tapes to hold the brief in place. Each landing zone takes up a substantial portion of its associated side panel and contiguous portions of the central region of the chassis and each includes a myriad of small (e.g., micro-sized) apertures or holes therein for breathability, e.g., to allow moisture vapor to pass therethrough. The sides within the crotch section of the brief are elasticized to fit around the wearer's legs and prevent the egress of urine therefrom. The top or waist section of the front panel and the top or waist section of the back panel are also elasticized to hold the brief snugly about the waist of the wearer.
