Wow! With all that gear in your canvas briefcase, do you have any room for work stuff? I'm afraid that my briefcase (a canvas bag with shoulder strap) is full to the brim with papers, books. lunch, coffee thermos, etc. I have most of the stuff on your list in a separate "get home" bag in my office, but for walk around readiness I rely on that M-1 belt pouch filled as described in my original post. That pouch is usually in my briefcase, but if I'm wearing a jacket and expect to be out and about a lot I may move the M-1 to my belt. On my key chain I have a Photon light and a REI whistle. In my pocket I have a bandana. On my belt I also have a cell phone pouch that has room for an all-weather pen and several sheets of all-weather paper.
