As an I'm-trapped-in-my-home kit, it's seriously lacking. As an I'm-lost-in-the-woods kit, it's pretty good. The greatest weakness i see with the kit as it is is the lack of a knife or any kind of food. I realize calories aren't part of the emergency needs over a 3 day period, but i'd still add an energy bar or two.
I'd go one-up on the bandanna and and replace it with the survival bandanna. equally effective for signaling, tourniquet, etc. with the added bonus of lots of useful info printed on it.
The page says there's only ten inches of nylon cord; i'd carry more, or omit it and carry more paracord.
