"...That must be one big cargo pocket..."

I've gotta agree with that. I love pockets, I pretty much live in BDU's (but not cammo) or civy cargo pants, and I can not imagine carrying that much stuff in them. Even if strapped to the leg, the bulk and weight would probably drive me nutso in a hurry. I am not saying that you might not be able to stuff all of that gear in (I would like to see the pot from the mess kit), but it just doesn't seem practical to me...
