The bag for bugging out!

I would like some input on building the absolute best bug put bag. Due to recent world events and over a dozen mass shootings on Easter Sunday alone, I believe that all bug out bags should be bulletproof with a rating of at least level IIIA. I prefer level 4, even with the added weight, its well worth the added protection level. Nut jobs don’g take holidays off and many of them are using rifles. You’d need rifle round rated level 4 armor. I only want the best of the best for all of my bug out bag items. Please sound off on what you believe would make for the best bug out bag items.
