Abstract A disposable adult incontinent brief having an improved tape tab. The brief may contain as filler additives an encapsulated fragrance and an absorptive polymer. The tape tab is formed from a relative long, generally Z-shaped, self-retained, strip of adhesive tape. One fold of the Z-shape contains a suitably positioned release liner. The brief has particularly advantageous characteristics, including the ability for one size of brief to fit subjects of widely varying size, the ability to mask odors, and the ability to absorb increased amounts of fluid.
