I ordered my insert and the super fast shipping had it on my doorstep in a few days. The option to pay with Sezzle and split the cost into 4 interest free payments made the cost much easier to bear. The Vertx Gamut Checkpoint has an integrated pouch specifically for this kind of insert. The fit was very tight, but once in place, I don't notice extra weight or bulk. One tip with the Vertx Gamut Checkpoint...the backpack is wider at the top and is a little narrower at the bottom. The panel, based on the orientation of the label, is wider at the bottom and narrower at the top. I had to insert the panel with the label upside down for the best fit. This is no problem as long as you pay attention to the side that is supposed to be facing outward. I hope to never have to put this in between myself and any bullets, but I know the protection is there if I need it.
