Abstract: A compact yet expandable waist belt with a pouch preferably formed from a single piece of seamless elastic fabric, designed in some embodiments with pleats in the back, that remains taut around the wearer's body during even the most rigorous physical activities, whether the pouch is holding one smaller item (such as a key) or multiple larger items (such as a cell phone, mp3 player, and/or money). When empty, the pouch is preferably approximately the same width and thickness as the belt holding the pouch in place, and yet the pouch's internal volume can expand up to 300-400% or more to hold larger items or a large number of small items. The single pouch is sealed with zipper or other fasteners such as Velcro® allowing users to access belongings quickly and easily.
