mine is Wallet, Keys, Phone, (ear)Buds, Mask, Hat; then i also pick up my backpack that has everything in it that i would need to restart my life from scratch and bring that with me too.

active prescription medication, insurance info, medical records, notarized copies of identifying documents (the originals are in a safe deposit box admittedly), my core set of electronics and their infrastructural bits (chargers, cables, I/O adapters, input devices, batteries, storage, a small fold-up solar panel), basic hygiene supplies, first aid kit, water purification tablets, a mess kit, waterproof matches, a leatherman multitool, 50' of 500lb rated paracord (it's purple! :D), an 8'x10' tarp, my towel (obviously of course) and a thousand dollars of emergency cash in a hidden pouch inside another hidden pouch. (edit: oh right i also have several single serving pouches of jerky in there for emergency nutrition if needed)

it's not nearly as heavy as i expected it to be so i just kinda lug it everywhere. There's even room for two spare changes of underclothes or one entire extra set of clothes, under and outer, should i bother to bring some.

the screaming 20s have been difficult and taught me to be ready to go in a moment's notice ._.
