I read years ago in some magazine---field and stream/Outdoor Life -- back when they had real writers and not this junk from today ---- create your own first aid kit cheaper --- found this out later in life away from this country, forget a marketing first aid kit - or an issued one -- make your own, put them where they can be accessed quickly.
Not in any particular order
Quick Clot Z--small scissors (don't overlook these when hands are numb from cold, falling in water, etc, easier to use than a knife)--duct tape, benadryl, space blanket, regular gauze and bandages (Israeli compression), and butterflys --CAT tourniquet and use timer on watch/phone--nitrile gloves (hands get dirty, can't wash them, you may need these), moleskin, I have antiseptic wipes and a small bottle of alcohol, anitbiotics, chest seal, marker, c card.
As others have stated, the stuff that is most life saving, goes in outer pockets for easy access, everything doesn't have to be in one bag, just know where it is ---
