Here are pics of what rides with me everywhere.
Keep in mind this bag does not ride around on my shoulder into stores and stuff. This is pretty much a trunk or passenger seat bag with extra goodies in it in case I ever need them. I also take it with me when I go on trips anywhere. Unless I'm on the motorcycle then I condense what I can into a Maxpedition Versipack.
Picked it up from LAPOLICE gear when they got a load of them in that were the wrong color. They were on clearance for like 20 bucks.
This stuff rides in the Velcro flap pockets on the front
This stuff rides in the two end pockets. The end pockets are big enough for those Nalagene (SP?) bottles.
This stuff rides on the other side of the velcro pockets. The bottom long tube thing holds a basic first aid kit I put together myself. The upper pocket holds odds and ends like my multi-tool keys, ect. The flashlight rides in a dedicated flashlight/asp pocket towards the top
And this stuff rides in the main compartment. Those are the main entrees out of a field stripped MRE. Enough to sustain me back to the house or to other means of food if I get stranded or what not.
Of course I've got enough room to add stuff when I see fit depending on what I'm doing or how far I'll be from the house.
ETA-on the side that the velcro pockets are on there is a "hidden" compartment for stowing a handgun or what ever you deem fit. It has velcro on the inside also for the mounting of various stuff such as Maxpedition's Velcro holster deal they have in their line. Works pretty good.
