I used the the XGK multiple times at -40 F without problems. Two of these babies side by side (needs a custom pot stand) will melt snow for large groups like you cannot even believe. You can set a 6 quart pot on top of it and start pouring snow in it from a garbage bag. Who cares about the noise it certainly keeps the bears away!David Metsky said:I've never had an MSR XGK fail to light or work like the blowtorch that it is. I've used them down to -20 F and I've never seen another stove melt snow like that workhorse. You can't hold a conversation within 20 feet of it, but I can talk once I have my water.
There is absolutely no need to carry something like that in summer, but in winter it's a godsend.
