This has some really good options for trauma kits, some pricy some affordable, https://emttrainingstation.com/best-trauma-bag/. Mine is pretty much like the third one but I added additional trauma kit with clotting agents (sponges), more gauze and tape. The nurse that came to the scene from a local farm nearby used most of my stuff including the gloves so we could keep it sterile. This investment paid for itself to me, if it can help one person down, it's worth it. I am adding a couple SAM splints to mine today.
