Thats why these folks will almost exclusively be carrying MREs (Meals refusing to Exit), hence no TP.

A full size down pillow (expensive but lightweight) with a down mattress from Exped ensures a comfy nights sleep. A good nights sleep is always underestimated in a crisis or survival situation simply because a relaxed brain is required to ensure the best decision making processes so as not to ensure that the crisis or survival situation doesn't get worse through poor thought and judgement processes. I've always wondered just how dangerous it would be hanging around these types of folks with their BOBs kitted out with 200 rounds of 5.56 and AR-15s who are constipated and haven't had more than 15 minutes sleep in the past 4 days really are.
