I have a Crazy Creek Thermalounger that I don't use. It measures 21" X 73" and will hold your Thermarest mattress and make it a chair. It is in as-new condition. I need some guying cord, preferably a highly visible color. I'd like to trade. I will also trade for a couple yards of silnylon or something like that.
I have a roll of 1/16" fiberglass wick for rolling your own Heiny pots (or Fosters cans) if you want to trade for that, too.
