I'm into lightweight hiking only. Those canvas tarps and tents seem pretty heavy. That SASS hootchie I mentioned is approx 700g. Combine that with a goretex bivibag of about 1100g and you have a degree of personal protection no tent can match. In sub-zero climes it's best to wear ventile cotton clothing. Maybe this is what you mean when you say he makes tents from very tight cotton. I'll probably decide on a quinze when I go to Lappland next year. Incidentally, the treeline in Lappland extends farther north than anywhere else in the world.
