A bandana(runny nose, pressure bandage, ear warmer, tie the four corners together and it is a hat), Tourniquet, (shoe laces, belt, suspenders), knife(splinters, thorns, cut up shirt for bandage), Camo vet wrap on my barrel will work also. A firstaid kit is the last thing I'd think about packing to a stand or in the field. I have stuff in the truck, bandaids, sewing kit for my clothes and pelts but will double for my body if needed, antibiotics and pain killers.
This has come up in the past, I leave the phone in the truck. I feel the more stuff you take to protect yourself the more likely your going to need it. I've been hunting, trapping, fishing mostly by myself for 60 years and have gotten myself into some pretty sticky situations and through the grace of god and common sense I'm still here and there have been some very iffy times.
