Alright, I'm sure this has been posted a billion times, but whenever I search for "first aid kit" or "first aid" it says no results found... Funny because one of the first topics on this board is about FIRST AID CLASSES.

Anyway... I have pretty much all of my gear. I've been putting off a first aid kit because I feel the standard kits are lacking in many areas. What does everyone recommend are essentials for an AT Thru hike?
