Abstract
Abstract A combination canteen and packframe for hikers employing the hollow tubing and structural members of the packframe to store fluids, such as water and fuel, and having closable apertures for filling and draining. The horizontal tubing of the packframe allows fluid to communicate from one vertical tube to the other, and a pump may be mounted in the packframe for pressurizing the fluid stored therein.
