The FAK is an Adventure Medical Kits "Solo" kit. If I remember right, I bought it at REI.

The survival kit is also in a second "Solo" pouch, but I pulled the first aid contents out for another kit. That left me with the empty pouch which seems to be just the right size for a backpack pocket or even a cargo pocket. (Plus, a pint-sized Ziploc freezer bag can cover the pouch *perfectly*.)

I also like the look of AMK's "Ultralight" series which comes with some Aloksak bags that I have yet to try. Hmm... the search for the eternal PSK container continues... <img src="/images/graemlins/cool.gif" alt="" />
