Without a bag, the small kit I pieced together is about $120.
6" compression bandage
quikclot LE z-fold
quikclot first responder 50 sponge
elastic bandage
CAT tourniquet
20F nasalpharyngeal airway tube
2x nitrile gloves
medicut shears
bolin chest seal
cloth surgical tape
Didn't buy it (yet) but that's a fairly good start with everything I'd need. I figure I don't need burn kits since you don't usually die right away from even a third degree burn, although some surgilube saturated gauze might be a way to pack a seeping burn...
