This is what a joke looks like to me.
And I can promise you that he is joking and that is probably his son's vest. They sell vests for men of this guy's size, and that is not it. Just google "fat airsoft".
But the "Shit Hits the Fan" survivalists are real. Idle minds masturbating about how well prepared they are in case society collapses.
I suppose it is more fun than comparing lawn mowers.
Think about what it means for a second, for shit to actually hit the fan once and for all. It means the death of the world. It means the death of dreams. For some people, dreams are already dead. For those people, the death of the world brings everyone else down to their level.
So of course it's what they're going to hope happens some day. They'll finally feel vindicated for never having made anything of themselves.
Guy knows his stuff. My only suggestion would be having the ability to place snacks on the back too, so your recon partner can easily grab supplies if needed.
