Embodiments include a pack bag including an outer container and an inner removable accessory organizer. The inner removable accessory organizer includes multiple compartments. The outer container includes an external easy-access portal through which contents of at least one of the compartments of the inner organizer are accessible. The pack bag includes a second external easy-access portal through which contents of another compartment of the inner organizer are accessible. The inner organizer includes a first pull handle to unfold and deploy the compartments when bundle straps are unfastened, and a second pull handle to fold the compartments one atop the other when the bundle straps are unfastened. When the bundle straps are fastened, the compartments are held together as a single bundled unit, such that the inner organizer is liftable as the single bundled unit out of the outer container simultaneously using the first pull handle and the second pull handle.
