I use any one of several shoulder different bags, depending on how much stuff I need to carry, so I recently got a Spec-ops Pack Rat for my essential gear, which I can easily transfer from bag to bag, or carry by itself. Right now, the Pack Rat contains the following:
-Leatherman Wave
-Leatherman Tool Adapter
-Bondus folding Allen wrench set
-Pocket Survival Pak (An excellent commercial survival kit, designed by Doug Ritter, containing Spark-Lite Firestarter & Tinder, Fox-40 Rescue Howler Survival Whistle, 2x3 Rescue Flash Signal Mirror, 20mm Survival Compass, 26 Duct Tape, 6 Stainless Steel Utility Wire, 10 Braided Nylon Cord, 50 #69 Black Nylon Thread, 4 medium Fish Hooks, 2 Split Shot, 1 Snap Swivel, Heavy Duty Sewing Needle, 4 Safety Pins, 3 Heavy Duty Aluminum Foil, #2 Pencil and Waterproof Notepaper, #22 Scalpel Blade, Survival Instructions, and Fresnel Lens Magnifier, all in a 4 oz., 4x5 waterproof pouch, to which Ive added a few things, such as waterproof matches, water purification tablets, and a couple of latex water bags, ie: condoms)
-Pocket Medic (commercial first aid kit, containing assorted bandages, towelettes, ointment packets, and analgesics in a 4x4 waterproof pouch, to which Ive added glucose tablets and a few other meds and supplies)
-25 550# paracord
-Small EMT shears (small, light, cheap, and cut just about anything)
-Two heavy duty trash bags
-Two ziploc bags
-Photon microlight (white & red)
-5 yellow chemical lightstick
-Bic lighter
-Moleskine notebook
-Pen/pencil/sharpie
-Blood glucose test kit
-Chapstik
-Dental floss
-Extra 1911 magazine
-Zeiss Miniquick (5x monocular)
-Small hair brush
-Fingernail clipper
-Spyderco Endura Stainless & SureFire 6P (I always carry a SureFire E2 and a folder, so these are backups that I can eliminate to lighten the kit)
Some of this stuff is admittedly a bit over the top, and I'll probably eliminate a few things to save size and weight, but I was having fun putting it together, so what the heck.
