Jeremy's bag certainly does look like the airport security. However, he is traveling with the acute pack and not the 7B pack. One thing for sure, you don't want to be using this bag as a backpack. While it does have the ability, it's just not sensible.
I believe Joey L. uses a Kata bag for the 7B. I'm sure you could find the model easy enough.
That said, I store my 7B kit (lighting only) in the airport security bag and roll with it. Needless to say it weighs quite a bit.
