New-be here loves this EDC string...
Blending-in is pretty easy here in the Midwest where a farmer in ancient coveralls walks with the well dressed business person; it's a sight you get used to. It must be business dress in big cities where a belt pack might stand out most. Here's an option, a "Karate Ankle Belt" designed to carry weights in separate internal pockets.

It looks a bit bulky but I'll bet an industrious person could come up with a working EDC ankle-bag design that would both fit and conceal more stuff, and also allow the business man to carry without having to wear a belt bag. So how do we accommodate the business dress ladies with their EDCs? How about the poofy hair styles from the 60s? The EDC wig, or platform shoes made by Leatherman?
