In an office environment, I use an Eagle Creek briefcase, the type with stow away backpack straps. It has room for my lunch, rain jacket, FAK, multitool, Clif bars, headlamp, water bottle, etc. with room for work related items as well! It has some compartments, but I suspect not as many as you prefer. A little stitching will solve that problem.<br><br>I think there is such as thing as "over compatmentalization" - I like to carry first aid items loose, for instance.
