Abstract: A combined liquid dispensing and item storage system with an orally activated valve. The system comprises a collapsible container for liquid that incorporates integrated auxiliary expandable storage pockets. The system is removably secured at a location on the back between the shoulders. An externally accessible fill port is covered by a flexible embossed foam panel held in place by shoulder straps and which panel protects against the discomfort of the fill port cap against the back, insulates the liquid, and provides air channels to vent and dissipate body heat. A length of flexible tubing for delivering the liquid is attached to the collapsible container, then routed through a slot in the auxiliary expandable storage pocket, over either shoulder, and held near the mouth by adjustable orienting holders attached to the shoulder straps. The orally activated valve is located at the end of the flexible tubing which delivers the liquid from the flexible tubing to the mouth.
