I have my first aid kit in one of those M-3 Medic Bags, divided up into categories in seperate aloksak bags, and while I thought it would be a great set-up in theory, in practice it turned out to be a bit of a hassle.

All of the zipped compartments are a pain to dig through if they're even moderately full. If you're not planning on stuffing the bag to the gills (is that a mixed metaphor?), you might be happy with it.

As someone else noted, the bag tends to hang awkwardly from the shoulder strap, but since you're not planning on using it, you're fine there.

A bag that zips open with the "box lid" design may allow you to browse the contents without unpacking them and if it's comparmentalized as well might work better.

In the end, whether it's a PSK or FAK, I prefer to be able to leave the contents I'm not in immediate need of in the container while retrieving what I do need rather than have to dig everything out and repack.

Maybe I'm looking for a man-purse instead... <img src="/images/graemlins/tongue.gif" alt="" />

If you do buy one, check ebay. I got one there for cheaper than most places listed online.
