Abstract: A flexible water container carried on the back of the user in a position that does not restrict the active movement of the user during exercise. Connected to the water container is a tube to conduct the water from the container to an irrigation system positioned within a helmet or otherwise placed about the head of the user. A pressurized air bladder is positioned adjacent to the water container in a manner such that pressure within the air bladder has a tendency to force water from the water container into the tube and thus into the irrigation system. The air bladder is inflatable by means a hand pump connected to the bladder through a flexible tube. The irrigation system is constructed and configured so as to appropriately surround the head of the user and further includes a soft, flexible wick material worn about the head for the purpose of conducting water forced from the irrigation system evenly about the user's head.
