I Highly recommend the First aid kit show-off thread. It was actually made for this exact reason. One good cheap supplier of FAK (First aid kit) materials is This Place*. It is were I got most of the stuff for my kit. I got enough stuff for a 20 person FAK, and enough stuff to resupply everything At least twice. I think the total, including bag, and shipping was 160, but thats only because it was a for a scout troop of 20-30 scouts, and I wanted to be able to refill it more than once with the materials available. i Highly recommend the "Make your Own route" as it is fun, its a learning experience, and you know you know how to use everything in it.
