Cooling vests go to Iraq
Approximately 500 cooling vests are currently being tested by soldiers driving armoured vehicles in Iraq and Kuwait. The vests are worn under body armour and a hose from each vest is plugged into the Humvee's on-board air-conditioning system. Liquid from the vehicle's AC system circulates through the vest, cooling its wearer providing relief from inside temperatures that can purportedly reach over 50°C.
