Depending on the kit and where it is being carried. I have had a premade kit in the past but soon figured out that I tend to use some things more than others. These days I make my own for the simple fact that I use what I know. The thing to remember is that you need to keep things in it that will keep YOU going if needed. Don't forget the meds and some superglue--I know, but I have used it before to get by.
