Abstract

An improved fecal incontinence leak prevention underwear or undergarment designed to address the challenges faced by individuals with fecal incontinence, including the risk of leaks and stains on clothing is described. The rear surface of the underwear or undergarment has a multi-layered rear surface adapted to cover a buttock region of the wearer. The multi-layered portion is strategically designed to extend from the crotch region to the cleft of a wearer. The multi-layered portion comprises an innermost layer made from moisture-resistant fabric, a middle layer of absorbent terrycloth material, and an outer layer consistent with standard underwear or undergarment materials, typically cotton (i.e., fabric). In one embodiment, the multi-layered portion has varied density to accommodate different levels of protection and comfort.
