This is my low level shit. What I keep on my plate carrier which I basically have set up as more of a 72hr ohshit kit than anything else

woven style emergency blanket
tp
dial soap for cleaning w/e
trauma shears
cravat
ETD

2x kerlex

Gerber Option 50 light (uses AA/AAA/CR123's, easier to scrounge batteries with)

It's basic, it fits in 5 pouches on my carrier (2 cumerbun, 2 big on the back, 1 multi-shit in the front) and is adequate for last ditch in combination w/ what I carry personally on a daily basis.
My pack carries more, sleeping system, clothing, etc... but there's overlap.
