This is a great kit. It comes with an elastic/velcro strap so you can attach it to the headrest on your car or other suitable location. I like the loops on the outside as you can slide trauma shears or a sharpie in there for quick access. It is bigger than the Operator IFAK pouch and holds a few extra things. I leave this in the truck and use it as my main trauma kit to supplement the Operator IFAK which is my EDC. When I did the THREAT course through Careflight I learnt that you need to have the ability to move quickly and take everything with you so the pouch system of this pack works a bit better than the zip-open clamshell design of the Operator IFAK. It's just a bit easier to jam stuff back in securely if you have to move. Both kits are great in their own way and contain the same items. Your circumstances will dictate the best one for you.
