The RollPack is one of the most easy-to-use saddlebags. Simply attach it under your saddle like every other saddlebag, but when you need something out of it. You take it off your bike, and just roll it out to have the best overview of what's inside! The three-compartment can be filled up with spare tubes, tools, and other stuff you might need. All perfectly organized.
Three compartments for innertube and tools
