I spent a lot of time in the military tents and I gotta tell ya they can be down right homey. Nice and warm with the old pot belly going. The squad tents and arctic hex tents are nowhere near as tough as the GP series so I would stay away from them. We spent some damn windy and cold nights down range on Ft. Carson in the GP's and they held up very well. I can't remember a single time one had a serious problem. They are heavy but if you could work some sort of bug out trailer into your preps I think that would be the way to go. Kifaru makes some lightweight teepee's but they aren't very cost effective. They do seem to be lightweight though. Here's a link to the site. Judge for yourself on these as I have no experience with them.
