useful instead of digging for stuff in pockets, i use it to keep my Keys, wallet, Cell-phone and wtv little small items i need,(also like splenda packets when dieting) sometimes pills...who knows... but i never wear it around the waist. just carry it in one hand with the belt strap thing folded in my palm. very practical, and alot less embarassing when its not around your waist.
beats forgetting stuff in your pants and getting it washed by accident.
