Thanks for that one, Neo!
I was anticipating a few more responses and hoped to answer them all at once..... I'm surprised that nobody else seems to be able to offer any experience with these mats.
My partner and I are moving to Qld soon, and I believe strongly in the whole 'Buy one to do it all' mantra. This makes it hard to shop for both Qld AND the cold conditions down here in and around ACT

....
In light of this, we are unsure whether the good old CCF solution will be enough to Tassie-proof a 0° rated mat when we do the Overland, but still keep that mat warm enough for Qld conditions. Let me know how you go with the CCF, cause it is at the top of my list at the moment (ill just buy a tough garbage bag to keep the CCF dry on the outside of my pack.... can always carry spare bags as backup!)
It is likely we won't be buying ANY mats until July, simply because that is when we can test out the Big Agnes for ourselves at Wild Earth in Brizzy (quick two week recon prior to moving)... Does anybody know of a Big Agnes stockest closer to ACT?
