That NRA bag looks remarkably similar to Oakley's bag.... and Oakley's bag has all the looks of a tactical heavy duty bag but it's kind of... imitation? I mean it's made to look sturdy but a lot of it's design doesn't serve much function.

I recently bought one of TADgears newest offerings but it just wasn't large enough for all the day to day back and forth to work stuff. Dispatch Bag It's really sturdy if you're looking for something like a brief case but it just doesn't have the volume to work like a small back pack. AND all of the molle webbing on it is pointless:
- back side - not going to attach molle pouches there
- inside pockets - not enough room to attach pouches there

So I went back to the same bag I've been using since 2000 made by Spire USA. They no longer have the exact same model I have (about 16 x 6 x 12), but it's lasted. Well thought out, plenty of room for everything I carry around plus lunch breakfast and more. Here are their latest offerings: Spire USA
What I'd really love to see is a marriage of the two above bags. I can't stand pockets/pouches and other details that don't make sense or don't efficiently use space. (google stomp II)
Maxpedition has some great designs and really innovative ideas, two complaints I have are (1) their cordura/nylon tends to be really STIFF (2) their compartments/pouches tend to be really small (and coupled with (1) tends to be a pain in the neck to get in and out of) Gonna have to add a third but I'll call it an observation - they actually "overbuild" - so many layers of webbing/velcro/nylon for multiple adjustments/attach points has some of their items (like a radio carrier for instance) adding an insane amount of bulk to the item you're carrying.
Will try to post pics of all the above later, if not by this weekend.

edit: just remembered this company Timbuk2 they make really rugged bags, a little pricey when compared to the Spire
