A hydration system for backpackers or other athletes including a bladder, a filling opening, an enclosing cover and filling opening, a flexible line and a deformable valve to be held in the user's mouth. The cover is of smaller volume than the bladder to protect the bladder from bursting upon overfilling. The valve is operated by pressure in the mouth, usually by the user's jaw and teeth to open a slit and allow potable liquid to flow from the bladder through the line and into the flexible valve for the user's consumption. The slit is located in the side wall of a membrane having a reverse fold whereby pressure from the bladder, in the absence of user applied valve deforming pressure tends to close rather than open the slit. The line includes a quick disconnect fitting to allow the filing of the bladder from the line as well as from its own filler opening. The inline fitting also allows the insertion of other appliances such as inline filter, a "Y" connection to a second person's line and valve, a mister or shower head. The filling opening of the bladder includes a swivel elbow and seal to allow full 360.degree. swiveling to any desired direction position and effective sealing when tightened.

[ What is claimed is:] [1.] A personal hydration system for carrying potable water for hands free delivery of fluid to a user's mouth while physically active comprising:a bladder for holding potable fluid;a cover for supporting said bladder with an opening therein for access to said bladder;a line connected to said bladder for delivery of potable fluid;a mouth pressure deformable valve connected to said line dimensioned to fit into a person's mouth;said pressure deformable valve including an inlet port, an outlet port and a separator including a reverse fold separating the inlet port from the outlet port;said reverse fold including a slit therein extending substantially perpendicular to the direction of flow between the inlet port and the outlet port of said valve whereby deformation of said deformable valve opens the slit in said separator; andwhereby pressure at the inlet port from the bladder tends to close the slit.
