I just got my bug-out pack done. I have always had one, then I got married and priorities got skewed. I discussed with the wife "Hey let make bug-out bags!" After telling her what and why one would need a bug out bag, she was all about it (very cool family project). We both have (as well as my son) a 3 day bug out bag. Mine weighing in at a cool 49.5 pounds and the wife's at 38 pounds. My son's about 10 as he is still young. But being an old fat man, I am worried that after the end of my block I will start shredding my pack of weight (kidding). I am curious as to how heavy I should have it so a average man (woman) in average health (40 and 33) should be and still be able to bug out. I would really like some imput on this.
