Left thigh cargo pocket: Modified Doug Ritter PSK and leatherman juice multitool.

Right thigh: Cell phone in water proof/water resistant vinyl pouch and a knife (Mora 840. I sewed on a leather patch so the holster snaps on above the pocket. The major part of the holster is actually inside the cargo pocket, with only the handle and about 1" of the holster sticking out above the pocket. I also made a hole in the flap over that cargo pocket.).

Left pocket: Handkerchief, keys (including key chain light).

Right pocket: Vallet (as small as possible).

The location of each item has been very carefully evaluated: It should NOT in any way impeede motion. It can't be too bulky. And I must be able to take a fall without hurting myself on hard objects, so any hard stuff must be somewhere that I usually don't land on. I'm 100% satisfied on all accounts.

I'm also trying to integrate a plastic tarp, poncho or garbage bag, but so far I can't make it work without being too bulky. A work in progress...

If I feel like tumbling about a lot (such as when skiing, or lying flat on the ground enjoying my lunch) I'll move the stuff in my "normal" pocket to a more secure pocket, such as the small pockets on my anorack.

Oh, and the anorack has a whistle easily accessible. Usually I'll have a mini first aid kit in one of the small pockets as well.
