My EDC bag is a Maxpedition Condor , mainly used to carry an IBM Thinkpad + some doc/papers in the main compartment.
The front pouches contain cables, tools, writing instruments, power supplies for Thinkpad and tel., various odds and bits...
And there enough place to stash one of Doug's PSK, two or three garbage bags, a few lights.
When planing for an overnight or two, I add an M4 pouch as a toilet bag (+ batteries and lights), the main compartment of the Condor receiving some extra clothes, underwear etc...
Add a (single) sheath for sun glasses and a CP-M for a pack of Kleenex (just the right size !) and I'm set for the day <img src="/images/graemlins/grin.gif" alt="" />
