A system for carrying articles from a belt worn on the body of a person or other animate bearer comprises a belt or elongated member (20) with a substantially planar rail (30) borne on the outside surface of the belt and a carrier (50) for articles attached to the rail by a sleeve sewn to the body of the carrier. The carrier (50) may be free to slide along the rail (30) or may be secured at least temporarily to the rail. The carrier (50) thereby can be moved along the rail when worn on the belt so that the bearer can place the carrier (50) in a more comfortable or useful position with respect to the body of the bearer and secure it in that position at least temporarily.
