Hidden Armor and Weapon Back Pack

Did you ever have the need to conceal a few SAPI plates (aka armor) and a pistol in a backpack?  Does it need to be deployed in a rapid "high speed" manner?  Look no further, the product has come!  I think this is a pretty sweet product, although there is a noticeable break in the video when the mustachioed man is donning the vest.  I also wonder how heavy/comfortable this thing would be.  Anywho, this could be a life save when the zombies come out...
