A mini kit pouch would be a cool addition. I know that survivalsheath makes an ankle rig with a pocket for various kit like materials. I have a Galco ankle safe that I use when I am mountain biking to hold some cash my ID and a folding knife (usually a SAK). However, if I was trampleing through the woods, I like the idea of having a few things higher up just in case I have to wade through a stream or somthing.
