I keep a Maxped Falcon II, in my truck, as a GHB. I do use Ziploc bags in it to save weight and price. How often do I access it? Not very often. There's a pair of gloves in there I use from time to time, but that's it. The FAK is in a quart zip, most of the clothing is in a gallon zip, and I've got spare zips, and a contractor bag in there as well. I did buy some Huffy tool organizer bags from Home Depot that I keep things in. They come in a three pack, and they're very flat, fill well, and yet keep you from overfilling. There largest is a wilderness survival kit, the medium sort of a miscellaneous kit, and the smallest I keep shotgun shells. Of course, there are other things in the GHB. In my present EDC bag, a Maxped EDC Versipack that will likely change in the near future, I use two Mini EDC organizers and a Micro. One Mini is an Anker Battery Charger and related items, another is tool stuff (LM Wave, bits, lighter, paracord, tape, zipties, etc), and the Micro is the office compartment. I originally bought the Micro for something else that didn't fit in it, and so I've never found great use for it. I do wish all the EDC bags were made of that lighter Cordura. There's a Maxpedition EDC Organizer (the original) under the rear seat of my truck that has some mechanic's tools. I've always gone back and forth on stowing that in the GHB. Finally, I have a Eagle Creek Quarter Cube that I keep a Belkin travel surge protector, USB extension cable, Targus USB multiport, and some other technology items. I like the present EDC bag because I could abandon ship and flee, by foot, with my GHB and EDC rather easily. However, the practicality of my present EDC bag as a daily office bag is minimal. It won't store my tablet. It doesn't hold reference texts well. The three organizers I've got weigh it down. It works exceedingly well for Disney World trips, however. I think my next EDC bag will be a Vertx Gamut, and I'll likely use one of the Maxped Mini and an Eagle Creek Quarter Cube or two.
