Sleeping Pad confusion - inflated "to the max" or not? on 08/26/2010 15:07:04 MDT Print View

OK - I am getting confused here.
For "maximum insulation/warmth", should an sleeping pad be inflated as much as possible for maximum distance to the (cold) ground or quite the opposite because "air is a conductor of warm/cold", meaning more air in the pad = colder???
Thanks,
Sven

I think the more important factor is insulation, especially with DAM's. If your pad is under inflated and you're compressing the insulation, then you'll probably be colder.

But, I haven't really noticed a difference with my DAM. As long as I'm not actually touching the ground, I can adjust the inflation to suit my comfort and still stay warm.

My understanding is that in an air only mattress (Neoair???) the more air the higher the R value.

Air isn't the best insulator but none the less the larger the distance between the top and bottom of the sleeping pad, the slower the rate of heat conduction through the pad. Don't think of cold air as actually existing, there is no such thing as cold only heat.

From personal experience and the science, I know that more air is warmer in my NeoAir.
