Abstract: A fluid storing and supply device includes two fluid containers supported within outer pouches and a conduit extending from each fluid container through which liquid contained in the containers can be consumed. A harnessing arrangement for harnessing the device to the body of a person which includes straps of predetermined length whereby the pouches can be suspended on a person's rib cage with one pouch abutting the person's chest and the other pouch abutting the person's back. Further straps permit tying of the positioned pouches to the rib cage in a manner that the pouches bear upon the rib cage so that a substantial part of the pressure exerted by the weight of fluid stored in the fluid containers is distributed over the surface area of the rib cage borne upon by the pouches and the harnessing arrangement.
