I will have to check which of them come in the 66 inch length. I am also only 5' 10" so would probably be perfectly happy with a shorter pad. I wish someone made an air mattress in the wider widths but shorter. All of the shorter pads are also in the narrow 20" width.

But I really need to try and keep costs down right now. As I said I will be doing my backpacking during warmer weather and don't see any need for a high R value right now. I don't find the CCF pads comfortable at all which is why I am looking into air mattresses.

I sure wish someone who has tried the Singlis would chime in. If that is a reasonably decent mattress I can't see paying a fortune more for little or no advantage.
