Abstract: A bag carried by a user, comprises at least one compartment sized and shaped for carrying articles. The compartment is defined by a front panel, a rear panel, a bottom panel and at least one side panel which are joined together via at least one joinder line. The side panel extends along each side of the bag and across the top of the bag. At least one securement loop is connected to the bag to extend across a width of the rear panel. The securement loop is configured for selectively attaching the bag to a selectively extendable handle of a wheeled article, and for preventing the bag from shifting and interfering with a maneuvering of the wheeled article.
