I used an Eagle Creek (IIRC) ankle pouch : OK for discretion and style !
And you can stash a lot of gear in it.
but :
- I really hate velcro .... after a few weeks of daily use, it's almost useless ....
- if you intend to carry it during summer, you have to wash it frequently as it makes you sweat quite a bit and soon it stinks !
( and now, I have one calf slimmer than the other ! <img src="/images/graemlins/grin.gif" alt="" />)
