You can get those suits now, the problem is that they require a water tank, pump system to circulate the water, a heat exchange system and power supply. Not something to easily where on a day-to-day basis and in most situations but IIRC NASA uses them in spacesuits. just like monty you get a tear in a line and the system fails. a quick search and you can get a vest version fairly easly for $300 or so with a backpack for the required equipment.
