Ding, ding, ding! Maxpedition Jumbo VersiPack with contents. My EDC when i am not staying at work for my lunch hour:
My contents:
Leatherman Wave
AMK Pocket Survival Kit
First Aid kit in waterproof pouch
Mora knife with tinder, mag block/flint steel, and knife sharpener (Dog Bone)
Poncho
32 oz Nalgene
GSI SS Bottle cup on the bottle sleeve
SAS Survival Guide (Collins Gem version)
Extra tinder canister (not in picture)
All these items are stored in the rear pocket, front pocket, lid pocket, and side pocket. With all items stowed, the entire main compartment is still wide open to accomodate lunch, extra supplies, etc. Its a good pack for toting around, but I did use it on a long weekend camping trip in place of a day pack, and I found it didn't meet my needs so weel for that application.
Loug does have a good point about stowing important gear in the detatchable top lid of a pack. that usually where I put items that I want to get to in a hurry, and I know that if need be, I can detatch the lid quickly and scurry away from danger faster than if I was wearing the entire pack.
And regarding keeping things on your person, yes, that is an excellent point. I try to do that with smaller, more basic items. I don't always wear BDUs or similar garb, so pocket space can sometime be at a premium, and thus dictates what I carry on my person. I tend to not weigh my belt down with gear, asn far as wearing blades, multi-tools, etc. But, that's just me.
