Riding around home I just keep a small assortment of tools in a seat bag but I'm planning a month long tour this summer and plan to bring a much more comprehensive set of tools. I'm thinking that I'd like some sort of zippered bag where I can organize all my tools and spare parts in one place. That way when I go to make any repair I can unroll all my tools and parts and have them all laid out in once place.

Anyone know of a nice lightweight tool bag that will be useful for holding a good collection of tools that can then be dropped into a larger bag or pannier?
