I follow Adam Savage all the time on his youtube channel Tested that guy is living the dream I tell ya, he got to troop with Chris Hadfield in space suits! anyway this set up looks so easy to make, its simple and can be made at home, just fit it in the Jetpack. I have this already on the back burner as a possible mod, it can get dam warm in the Fett outfit, it's not so much the heat it's the humidity thats a killer urghh
take a look at the video it's only the first few minutes you need to look at
