I noticed the R value of the kickstarter pad. But at 3+ inches it has to be above R:1. My guess is they haven't tested it so just to be safe they have put an R value of 1. Just look at other bags or pad at similar thickness and their R value should at least be in 3-4 range.
- dnr 13y agoYou need a lot of interior baffling or insulating material stuffed inside an air mattress to get the R value up to 3 or 4. In a big open tube you get convection, which speeds up heat transfer. Note that the original NeoAir, which is about the same thickness, is only R 2.5, but that's with a lot more interior baffles plus reflective coating on the inside. The exped mats are filled with down or synthetic insulation.
