Picked up a Versipack when they first came out, was too small for anything that I needed it for so I ended up using it to carry a USGI Vehicle First Aid kit and added some extra items. This is what I keep in my truck aka "POV".
Stuffed in with disposable blanket:
Bottom row of items are what's in the FAK, top row is what I added: Vac packed kerlex, 14ga caths, Disinfectant, J tube, Sam Splint, Ace Wrap, Bungee Cords
leg panel for GSW/etc. The left is CSM Gear, the right is North American Rescue. The NAR is WAY too big if you asked me. These are meant to be worn on the leg and something that bulky (next picture) gets hung up on stuff, esp in and out of vehicles.
Got this next one "pushed" as part of a new COMPLETE package about a year ago, had been meaning to migrate the USGI FAK out of my Versipak and into it so today was an opportune time.
Thought I had a picture of her closed up but.... added a roll of Coban, two cinch tights, another vac packed kerlex and a unvac'd one, another ace wrap, another 4x7 with cravat(can never have too many). A little larger but I like it. For the life on me I can't figure out what they had in mind with all the fasteks... Recon Mountaineering LLC btw.
edit: can't forget the surgical stapler!
