Abstract: A runner's portable water supply is presented. The supply comprises a water bottle with a special cap and sipping tube. The sipping tube is curved and only slightly flexible so that it can be bent, but retains its shape if the wearer does not bend it. The cap fits into the bottle neck in a liquid tight coupling and has a first interior surface slideably mating with the tube in a substantially liquid tight coupling and has a second interior tunnel permitting gas to enter the bottle but deflecting liquid so that liquid cannot splash out of the bottle. The bottle is coupled to a selected part of the wearer's body with the upper end of the tube near the wearer's mouth and the lower end of the tube near the bottom interior surface of the bottle. Air flows into the bottle as liquid is sipped out. The bottle need not be held.
