So I am a EMT-B and work for the Fire Department, what I am looking for a FA kit for my truck and one that I can take into the woods with me. The problem I am running into is right now I have a large backpack that is my kit and I am haveing a hard time making it smaller. We run a complete jump bag off the fire truck, so I don't really know what is the need only items. Also what size bag does anyone use?
