I will state unequivocally that the only 4-season model(s) you will see from us will be double-wall. I don't like to be cold and single-wall shelters are just too cold for me in cold weather. Not that double-wall shelters are exactly warm in cold weather but they're warmer than single-wall and every degree helps. YMMV.

Now, can you all please just let this thread die with peace and dignity...
