Abstract: A portable carrier for transporting necked bottles includes a tubular housing with an open end configured to receive a bottle, a lid configured to fit over the open end of the tubular housing, and a neck protector disposed within the tubular housing and defining an opening for receiving the neck of the bottle. The tubular housing preferably includes one or more sheets of a high-density, closed-cell sponge material formed into a hollow cylinder with opposed longitudinal edges, and further includes an adjustable fastener such as a zipper for selectively joining the longitudinal edges of the tubular housing together. In a preferred embodiment, straps or other types of cinching members extend circumferentially around the tubular housing at longitudinally spaced locations to permit the diameter of the tubular housing to be varied along its length to accommodate bottles of various shapes and sizes.
