Is It Warm?
The fabric quality of a sleeping mat does not always mean it denotes to the warmth of it as well. Some of the best sleeping bags do not have enough insulation. With these, you are left there to have the temperature of the ground suck your body heat in very little time after you have gone to sleep. It is even possible that you may not be able to sleep at all.
The R-value is a word that you may hear a lot in gear stores, but what does it mean? The R-value has to do with the insulating quality of a mat. The higher this value the higher the insulation. The R-value has been around for a myriad of years and was once the only way manufacturers would label their mats instead of testing it out for other factors.
