I have 4 of these - Condor Outdoor Rip Away EMT Lite Pouch

Mirroring what Todd said, these are the prefect size for an IFAK. In mine I have 2 chest seals, quick clot, Israeli bandage, booboo kit and attached to the side molle, a TQ holder, CAT, and med shears. I have these on plate carrier #1, another I move between plate carrier #2 and a range belt, another in my EDC bag (velcro part), and another I move between my truck and shooting range back. If you want to carry enough med supplies for 2 people, definitely go with the bigger Condor rip away pouch. A rip away med kit pouch is the way to go, and this is the best value option to go with especially if you are running several IFAKs and at different locations and situations. On a side note, I stagger change out items every other year, i.e. chest seals and medicines which have expiration dates.
