The six (6) outside pockets are fairly small, and have a simple flap with a small tab of hook & loop. I don't use these pockets for anything too important because they are to to get things out of (probably because of the raincoat behind them). Tape (re-rolled onto a nail to save space), a small first aid kit, a fold up stove and fuel (to boil water), a rifle / pistol cleaning kit (spare for hunting trips) and matches Gina  waterproof container fill these pockets.

The bag unzips around the entire perimeter (either way, two zippers) and the bag opens like a book with the tools organized on the right and large pockets to the left. The "Tools-In-A-Row" system folds open, then open again to layout your most-used tools. This lets the bag keep tools organized, but it also makes it hard to get in and out of the bag for a specific tool. I keep a can of tire repair and fill inside this emergency bag as well as a cheap ball cap with a brim (I live in the desert). Everything else inside is still contained at this point.

On the left side behind the front of the bag there are two large pockets and a hook and loop tie down. I use the tie down to secure a warm cap, and two pair of gloves (warm and leather work). There are clean rags and bandanas in these pockets and a large raincoat which really fills the large pocket which is probably designed for paperwork, etc

20 Inside and 6 outside pockets organize a wide variety of tools and accessories. I keep a few socket wrenches, a few nut drivers, a couple of crescents (large and small) Wire cutters, long nose, lineman's pliers, a variety of screw drivers a few light sticks, zip ties, wire and a knife

All loaded this bag and gear weighs just 17 pounds. worth it's weight in gold if it save you the time and expense of a tow
