A mobile back-pack for sports or military use is disclosed. A back-pack is devised in the form of a cabinet having the shape of a trapezoid, the cabinet being rotatably secured to a disc. The disc is dimensioned so as to permit an operator to grasp a handgrip railing at the top of the cabinet and then propel the disc at the operator's side. The cabinet glides smoothly within the circumference of the disc, riding on a peripherally positioned track within the disc. A battery powered motor and drive wheel propelled version of the mobile back-pack is also disclosed. Built-in support legs provide stability for the mobile back-pack in an upright, stationary position. Door latch secured trays within the cabinet provide for storing items to be transported, and for easy access to the items when needed.
