Like MDinana, I carry a variety of things depending on my environment, activity and expected duration, always with back-up. (i.e. A dayhike means being prepared to be out for a night or two, depending on where I am.) My minimum carry, regardless of where or what I'm doing, is my urban and wilderness EDC. It's always with me and on my body. I migrate that gear between my "purse" for urban and an Obusform "Breakout" fanny pack (no affiliation) for wilderness or active urban activities. It weighs maybe a pound or two, more when I clip on a full 32 oz. water bottle.
