Our point was that out dad's own fanny packs

. Not that they play airsoft.
I found this picture of ghost's load out. At least one of these chest rigs was made (as seen in the picture) I think it is a knock off, of the MK2. Their is a zippered pouch across the front (making it clearly not Tactical Tailor) The original straps have been recovered with wider shoulder pad style straps that have D rings attached. Weather or not the one in the picture is MOLLE\PALS is up for grabs, but it looks like its sewn together.
As for the DBL strap across the back question. I only found one picture with the double strap and I think the second set of straps were either some sort of weapon sling, or just double re-tension straps for distribution of weight. However I cannot find that image again.
