Well, I am a sucker for kits.

Comments/questions:

Aren't hygiene items part of your BOB?

Isn't at least one change of clothes, including shoes and hat, part of your BOB?

If you have a BOB, would you tie up a hand carrying a gym bag like this?

What about at least rudimentary first aid stuff? Water purification and a bottle or two? Extra charged cell phone battery?

I could go on and on but I guess I do not see why you would not just grab the closest thing you had to a complete BOB in a backpack. Please beat me up on this point.
