A safety-monitoring garment system is used to thoroughly monitor the health and performance of a user. The system includes a garment, at least one health-monitoring sensor, at least one performance-tracking sensor, a microcontroller, a user controller, and a portable power source. The garment is preferably a jacket for the user. The at least one health-monitoring sensor continuously monitors the vitals of the user, and the at least one performance-tracking sensor monitors the performance status of the user. The microcontroller stores, analyzes, and delivers the data from the at least one health-monitoring sensor and the at least one performance-tracking sensor to an external computing device. The user controller manages the at least one health-monitoring sensor and the at least one performance-tracking sensor. The portable power source provides the necessary power for the at least one health-monitoring sensor, the at least one performance-tracking sensor, the microcontroller, and the user controller.
