Just curious to see what others who go on long distance tours use for hauling their tools. I plan on disappearing for a long time (1-2 years) and am trying to make sure I've got all I's dotted and T's crossed. I'm at the point where I am deciding what I should use to haul tools/spare parts in, and would like to maximize the space I have underneath the saddle. All the undersaddle bags I have found are not waterproof, and have a tendency to leak, which means rust on my tools.

I put my tools/parts in zip lock bags and store in my panniers. These are things that I don't need on an immediate daily basis. If I need them I open my pannier top and slide my hand in to feel for my tools bag. In any case, zip lock bags keep your tools dry.

The Ortlieb bag is not as big as one may think.
I have a large size and it fits neatly under a Brooks Champ Flyer.
Mine holds: tire irons, a tube, patch kit, multi tool, a leatherman, and a small rag (which I lay nuts and stuff on so I don't loose them on the side of the road).
