Should I get a compact glove-box kit or a full trauma kit?

It depends on use. A compact kit handles the everyday cuts, blisters and headaches most drivers actually encounter and stows easily in a glove box. A larger IFAK or trauma kit with a tourniquet and chest seals is aimed at serious roadside injuries but requires training to use effectively. Many buyers keep a small kit in each vehicle and one larger kit for road trips or off-road travel.
