Question for those that do or have used blow-up (not SI) pads as only under insulation in a bridge; what & why is your preferred choice?
My needs; 24"-26"W by at least 70"L & 2"-3"thick. I would like to be able to handle below freezing if possible but do not know how temp ratings or R-value's equate in the real world with air under it instead of ground. I am value, comfort orientated & relatively warm to hot sleeper until I get cold .
My search has me looking at these but I'm clueless.
