I am hell on air pads! My current one is the only one that has not leaked at some point or another. I carry at least one, if not two squares (2x3 and 2.5 oz) of cheap blue pad to use outside the tent as sit pads and as back up. My current pad is an x-small (8 oz) Thermarest Pro-lite. This one seems to be working well. I just wonder if there are big variations and quality control issues in the manufacturing of these pads.
