These overpants are brilliant. My husband has Parkinsons, and the incontinence problems that come with it. These waterproof pants enhance the pull up continence aids he wears, and save the bedding from getting wet overnight. He wears them under daytime clothing, just as an added precaution, if we are going out for an extended period. Obviously there are the odd occasions where leakage occurs, but nothing is infallible. The staff at Wonsie answered my questions before I ordered, and the ordering and postage processes were uneventful, and prompt.
