Actually since it should provide insulation there should indeed be an r rating. However since the down is compressed under you instead of being say inside the air pad the rating would be quite a bit lower, nearing 0. With the said. Figure out the what the shell is made out of and then you can figure out how much 650 down is in it. I'll guess in the 1lb unit it's about 6oz of down. without your body weight that would be an r value of about 3-4, add your weight and you're at 1.5-2. I'd just go ahead and pick up an exped downmat if your goal is warmth and maximum r-value.
