There are several items that should be an everyday carry. A pistol preferably a concealed carry, with your license of course. Your cell phone fo comms, and a tourniquet or individual first aid kit (IFAK). According to recent studies 35% of pre-hospital deaths are the result of bleeding, which make knowing how to stop the bleed, and more importantly carrying a tourniquet an essential #EDC item. There are several tourniquets you can choose from when selecting a tourniquet. The best tourniquet is the tourniquet that you determine is right for you. Committees, organizations, units, and others all have some merit if they recommend a particular item; you should remember that none of the above are beyond corruption or having financial or other conflicts of interest though. Therefore, don't except what someone tells you as the gold standard immediately. Do your research and test some tourniquets so that you can find the right tourniquet for you.
