Why on earth would you bother with armor. If it's cheap and light, it'll barely stand up to .22, if it's heavy and strong, a big, well placed round will still beat you up. In a bug-out situation, you want to have mobility on your side. Your torso is the most important area, sure, no argument there, but... y'know what, here-
Video of some idiots shooting their friend wearing a vest, 9mm, fewer than 10ft awayHe's wearing a "bullet-proof" vest that wasn't so bullet-proof. If you get hit in the plate, it WILL hurt, less so than without armor, but you will STILL need immediate medical attention. The pros and cons of armor just don't match up. A simple small vest weighs roughly 6lbs, and at best it will stop 9mm. But if someone SERIOUSLY wanted to kill you while you were hiding out somewhere, do you honestly believe that they would bother for a torso shot?
