In the front I carry my fly box, clippers on a cord, tippet spools, hook hone, compass, small flash light and other odds and ends. In the rear I carry water, a small first aid kit, water proof matches and a sandwich bag full of dryer lint. (it's a great fire starter). A small camping mirror, hand held flares(smoke) a whistle, a pocket knife,and some times a little nosh. I also attach a pair of medical shears to the strap of my vest. They cut through just about anything. It may seem like a lot of stuff, but I've been stuck out in the middle of no where before. Some of this stuff has come in pretty handy.
