Left front pocket:
Keys (Fox 40 and Hot Spark on ring also)
If I am wearing my Leatherman Sideclip it goes clipped in that pocket.

Right front:
Wallet (with fresnel lense, info sheet, Swiss card light, laminated tinder)
Bage wallet (with lock picks)
Benchmade 921-BLK clipped in pocket
Lighter in the mini-pocket.

Right back: Bandannas
Belt Left side: Innova X5
Belt Right side: Cell (camera) phone
Leatherman Juice Pro or Wave (instead of Sideclip)

If I an going into the woods or on a trip I have a small belt case with my Altoids PSK, a black garbage bag, and extra batteries for the X5.

I find it doesn't weight me down too much as long as I am wearing good fitting pants.
