The chief distinguishing feature of a winter sleeping pad is the sleeping pad R-value. R-value is actually a construction term that refers to the insulating properties of, in this case, a sleeping pad. The higher the R-value, the less heat you will lose in to the ground at night.
The best winter sleeping pads are actually padded with insulating material, such as down, to help trap and reflect the heat that your body gives off. This supplements the insulating capabilities of your winter sleeping bag and keeps you warm in toasty at night.
