A couple items I rarely see in packs and I apologize if they've already been mentioned.

Guys, get a super absorbant Maxi-pad. Can you think of anything that will cover a gushing wound better?

Dental floss. First off, I hate having something jammed in my teeth. Moving past that, floss can be use for so many things I won't even list them.

It's extremely strong. I use it on my expandable broadheads when sighting in. Just 3x around and it keeps the head closed for several shots, hitting a broadhead target, at 260fps! And I don't even tie it. I just wrap it around and it holds very well. It's light and takes up little room. I like the small Glide container myself.
