To pump-condition a garment that covers at least a portion of an individual, at least one fluid-circulating vent panel circulates a fluid adjacent the garment in an effort to condition the individual. A pump provides a motive force to circulate the circulating fluid through each vent panel, and a conduit is routed within the garment and couples the pump and each vent panel. A controller controls the pump to provide the motive force, and a power source provides power to operate the pump and the controller. The pump may be an ultrasonic piezoelectric pump.
