Abstract: A sports ball bag provides for the drying and warming care of a sports ball during the course of a ball game. The bag is particularly adapted for the care of one or more footballs placed therein, as would be used in the play of amateur and professional football games, but may be used for the care of balls used in other types of ball games as well. The bag is formed of a waterproof outer cover (e.g., vinyl) having an openable side closure and opposite openable end closures thereby allowing the cover to be laid out flat. A removable and replaceable moisture absorbent liner (e.g., a terry cloth towel) may be secured within the cover in order to dry the ball and to provide some thermal insulation properties. A warming device, such as a chemical hand warmer packet, may also be placed within the bag to warm any balls or other articles placed therein. The end closures are preferably draw strings in order to provide rapid access to the interior of the bag.
