I recently acquired an HTC Blowout Kit. Based on my (limited) experience of pouches I have seen so far, this is in my opinion the best thought out, and the most suitable design for general use including civilian wear.
The link to the HTC site is:

PROS:
- well built
- well positioned in the lower back with access by either hand (yet flat enough to be comfortable to lie on your back while wearing it)
