Some of the best innovations in the world are things that seem ridiculously simple in retrospect. Israeli field bandages are a good example. They seem so natural you wonder why it took people so long to come up with the idea. That is a sign of good design.
You can go here to learn about them. I particularly recommend watching the training video (unfortunately it is QuickTime so I can’t direct link). It will give you a good idea of why Israeli field bandages are becoming the new standard for military medics and other first responders.
