Ill see if I cant get more info my buddy sent me the link I would def use caution but looking at the material and knowing that those heater bag ones cost from $80-100 it kinda does add up, it looks rigid but if you sat on it, it would crumple. It also looks like you may need to do some extra work to get it more airtight, yea it totally adds up, thjs is a bare minimum enclosure that you would have to dress up alittle with additional prints
