Ever since I got my "edc" bag (A walmart hydration pack) I been going back and forth between how empty I should leave it and now how empty I SHould leave other bags for other situations.

My Thought is What if I Needed to throw somthing in it while Im out and about OR add to it for certain situations. Right now its half empty and can prolly fit around a basketball amount of space.

SO whats your opinion? Do you prefer to leave it half empty with mid level preparedness almost empty with bare minimal preparedness or load it up till it bursts?
