Hey Mike, you know what I like, or think would be cool?
I have been using the heck out of the little rectangular stuff bags, the Kubes It doubles as either the tire kit, or toilet kit, depending on the trip
But importantly, I think it definitely keeps things from going loose in the backpacks. If I had three of them, there wouldnt be any loose stuff. The backpack becomes a stuffsack for smaller, nested ones. And each pack could be used independtly, without going spelunking in the pack just to find one thing.
I could either pull out the toilet kit OR the tire change kit, OR the maps, compass, keys and phone.
Just a word out to you guys looking to get a backpack. get two or three of the Kubes. It just helps my organisation a lot, because I tend to get a little spread out
