A personal cooling device that works in harsh condition to save human lives due to heat waves.

Rime Systems has developed a unique technology for helping keep people cool in climates with excessive heat. This product is a nylon cooling vest that users would put on in hot environments. Using thermoelectric elements, it disperses cooling across the users back to achieve a steady state heat transfer. This device is meant to be used in environments where mass cooling is scarce or ineffective.
