I love this bag. http://www.511tactical.com/All-Products/Bags-Backpacks/Patrol/Patrol-Ready.html
It's separated on the inside into 3 sections. I went ahead and bought some desk organizers from an office store to make them rigid.
Usual set up is like this,
Small square has kimwipes, and filters in it, back has hardmattes, full metal jacket, whip crank, hard tape, front has slate in it.
I use the front outside compartments for air, water bottle, and then i keep gum, altoids, hand sanitizer.
The sides I put other small tools I may need.
There's a nice piece of soft side on the lid, I keep my soft tape attached to that, also extra filter tags.
