Abstract: An elongate, flexible tether line connects to a life jacket a large, brightly-colored balloon that is easy for a rescuer to observe when it is inflated and floating in a body of water. The balloon is stored within an internal cavity of the life jacket in a deflated condition and is inflated upon removal from the cavity. A first end of the tether line is secured to a liner that forms a pocket in the internal cavity so that when the balloon is fully deployed, the liner is turned inside-out to prevent water from the external environment from entering into the internal cavity. A funnel is formed in the balloon and is in fluid communication with a downspout that is in fluid communication with a reservoir formed in the balloon. The funnel collects rainwater and the reservoir stores the rainwater. A drinking spout enables a user to consume the stored water as needed.
