I need to get serious and build my EDC bag (go bag, battle pack, or whatever you call it). What bag do you use, and what do you believe is valuable enough to lug around 24/7? I know a lot use Maxpedition products but I'm looking for ideas for bags that are more inconspicuous, or less "tactical" in appearance. For medical equipment/supplies, are kits from Adventure Medical any good? Or should I avoid kits altogether and build from ground up?
