The system, worn over body armor and a uniform, circulates chilled water through a vest that is worn directly against the skin or over a t-shirt.


The cooling system is designed to maintain the user's core body temperature at a safe level to mitigate the effects of thermal stress and extend safe mission duration at extreme ambient temperatures.


Rugged and self-contained, the portable cooling system can be mounted in a variety of positions on the body through the Modular Lightweight Load-carrying Equipment (MOLLE) attachment system in any orientation. The system functions properly regardless of the user's body position, i.e., sitting, standing, or prone.
