My thermarest looks like it has mold inside of it. I’m assuming it’s from the vapor when I have blown it up. Anyone have this problem or know how to fix it. I have replaced it with a foam pad because I have been freaked out to blow it up again. Is there hope?

Call Cascase designs and ask their advice.
Too late now but when storing inflatible pads after a journey I like to hang them up with the valve open in a room with dry air, like the furnace room for example. I do the same with all of my insulative gear and my sleep system too.
After a couple days or a week I pack everything back down into its own stuff sack and store in my gear rack; well except for the non-compressible like down.
You could maybe make a mild bleach solution and pour a little bit in the pad and shake it around a bit, and let that stand, then hang and drain.
I think it would be better to call Cascade Design. There’s a good chance they’ll replace it with a new one.
I store mine open at room temp, thinking it might dry out inside, but I think this is minimal – too small an opening, not enough air flowing
Sometimes I’ll let it sit for a day so any water vapor has a chance to evaporate from foam into the air inside, then roll it up to squeeze all the air out of it, then let it re-inflate – repeat a number of times. That might remove water from inside.
I’ve weighed mine occasionally over a couple years and any weight gain is minimal so it must not be accumulating significant water or growths
it weighed 16.2 ounces in July 2012 and June 2013
16.5 in April 2014, and January 2016
the 0.3 ounce weight gain could have been from one event – it was a little damp and some mold grew?
probably not scale calibration because I have a bag of coins that weighed 7.67 ounces on August 2013 and January 2016
