An improved hydration system for runners that provides superior motion control and easy dispensing. Fluid is contained within a flexible bladder and pack, and attached to the waist. The pack is constructed of comfortable, elastic, and thermally-insulating fabric. When attached to the waist, tension in the fabric compresses the bladder against the user and dampens motion. Uniform distribution of fluid in the bladder contributes to motion control and is provided by a flexible plastic compression plate and snap elements that pinch the lower portion of the bladder. The snap elements can be disengaged to allow the bladder to be fully expanded for easy cleaning and drying. Fluid is dispensed from a small waist-mounted squeeze bottle that fills automatically from the bladder via fluid coupling elements. Check valves ensure that fluid flows unidirectionally from bladder to bottle to user, and prevent air infiltration into the squeeze bottle and bladder.

A high performance squeeze bottle dispenser includes an internal product-containing bag which is in fluid communication with a dispensing nozzle. The dispensing nozzle is airtight to prevent air from escaping back into the bag when pressurization of the bottle is released. A one-way air valve in a wall of the bottle admits air into the interior of the bottle around the outside of the product bag to provide a pumping action which pressurizes the interior of the bottle to cause product expulsion through the nozzle. An inversion collar projects into the bag so that the bag folds inwardly upon itself and up into the collar as product is expelled. The collar may also include an upper inside dome-shaped surface which matches the shape of the inside of the bottom of the bag to achieve near-complete expulsion of product to reduce waste.
