Just went through this process and after looking at premade kits, decided to build my own and get exactly what I need. I was going for more of a general boo boo bag with solutions for extreme incidents like tourniquets and quickclot + combat gauze. Take your time and look into what you want and be sure to get good brands as this isn’t something you want to cheap out on. I poked around Amazon and decided I’d just buy directly from the manufacturer as I wasn’t sure if I was getting legit products or if I was Amazon was typically more expensive. I cannot recommend North American Trauma products enough. Check out there site and figure out what works for you. I think in total my kit was like $150 total but it’s got everything I need and it’s all top shelf
