I two altoids tin kits balanced in each front pocket. One is a FAK which sees weekly, if not daily, use and the other is a PSK similar to Dougs ( I have previously listed contents with pic's just search). I also carry a few other items, some on my key chain. I haven't reached the physics limit of having my belt fail to hold up my pants yet. <img src="images/graemlins/wink.gif" alt="" /> I have a swiss micro-tech+, swiss utili-key, small tubular whistle, small match safe, and ASP saphire light on my key chain, Cell phone on one hip on the belt and Leatherman wave on the opposite hip. I also carry a small multi-tool and a largish butane lighter on a split ring in my pocket and, to balance my rather large wallet, I carry a decent spool of tylon twine in my other back pocket. I find that I can carry this set of gear in jeans and in my suit without it being remarkably obvious. I don't wear tight fitting clothes and My dress slacks are pleated in front. I have considered those Docker e-pants with the extra concealed pockets but they are too expensive for casual pants and too casual for dress. I carry my PDA in my shirt pocket or vest pocket depending upon whether I have my vest on. If I am wearing my vest I have a bunch of other stuff as well.

I guess what I am trying to say is that if you are not wearing really snug fitting clothing then you can carry a bunch of stuff. OTOH, if you are wearing really tight jeans or slacks then a bulky keychain will stand out as much or more than a PSK which looks like a candy box.
