Cooling Vests from Army for use in Humvees

An armor-padded Humvee could prove too toasty for the crew inside, thus the Army has developed a cooling vest that are worn beneath body armor. These vests come with a hose that is plugged into the Humvee’s on-board air conditioning system, circulating liquid from the vehicle’s AC system to cool down its wearer – combating internal temperatures that could rise up to 130 degrees.
