An arcuately-formed reservoir, having collapsible, accordion-pleated sides, provides a supply of drinking water which, also, serves as a weighting medium. A compliant sheathing is used to enclose the reservoir therewithin. A pair of sheathed reservoirs are carried on the wrists of a jogger or runner. The reservoir has a closure cap, with a water-dispensing control valve therein, and the sheathing has an aperture formed therein through which the cap and valve protrude.
