releasable zip ties are a God-send! I agree, so many uses.I’ll admit in my 20s and 30s I didn’t carry a trauma kit but there’s no way I’d go out without it now, tourniquet / israeli bandage / etc is ounces.
One thing to add that I think is new, I always have some medium to long releasable zipties looped on my pack somewhere. I can’t even list the primary uses bc somehow they seem to get used all the time. Handy around the garage too, weigh nothing, don’t rattle.
