Given how sleeping bags aren't designed for daily use and how storing them compressed can ruin the loft (and one would be compressing their sleeping bag regularly if perma /out/ since having a fixed camp is a bad idea), what is a reasonable choice of sleep system if one was to go perma /out/? How long can one expect a sleeping bag to last under these circumstances and what can one do to prolong the life of a sleeping bag when perma /out/? Assuming one travels north and south throughout the year to limit the temperature range one has to deal with.
