I used to use an olive drab packrat as my EDC bag (with a shoulder strap made from the removed waist belt off my Maxpedition Falcon). I just found it TOO useful. I used it as a beach bag holding cd player, book, shades, suncream, water, cash, phone etc. Great piece of kit. Ive since changed to a Maxpedition Devildog, but since Im in business suit most of the time, I dont carry it like a fanny pack (WE call em bum bags! Fanny DOESNTmean bum in England!! LOL), so I tuck the belt inside the padded butt section & use the supplied shoulder strap, Looks "a bit" tactical but its trendy enough to not look too out of place. I carry a half-litre Sigg bottle in one of the mesh pouches, a blue glowrig on the top & all sorts of S**T inside it; SAS tin, FAK, Pocket size wash kit, lunch, car stereo face place, ANOTHER flashlight (got one on belt & one on keys!)
