Abstract: The invention is a reusable personal cooling apparatus that utilizes exclusively pourable pellet forms of Carbon-Dioxide Pellets as an expendable coolant. This coolant is placed in one or more compatibly designed, refillable Coolant Chambers that are integrated into a wearable garment that can be either a Hard-Shell Design (by example, an impact-protection helmet) or a Soft-Shell Design (by example, a vest), or a combination thereof. The Carbon-Dioxide Pellets are of machine manufacture and high density. They enhance the conformability of the Soft-Shell Design garment, promote ease of filling both garment designs and make possible the application of the pellet form of coolant to rigid, thin, curved structures like a helmet. The application of vibration expedites the speed of filling the apparatus and maximizes the fill volume by minimizing void formation within the Coolant Chamber.
