Yeah I have a largish ALICE/MOLLE type pack I used in the AF before they change the Camo pattern. It is the type that has a frame with kidney pads and I have a 3 day pack that attaches to it. This is where I am going to put the stuff I will need if I need to Grab and go.

I agree with the water... So I think I am going to try to find some collapsible containers to put in my kit, along with a pump filter I think.
