I use a mess bag. It's a chrome metropolis (which I know lots of people like to rip on because they're trendy or whatever but who gives a poop). I love it because it's comfortable. The one shoulder thing I love. I actually re-tried a backpack a year or so after I started the mess bag and I experienced major fatigue. It has attachment for a blinky, it's waterproof, and it holds all my stuff. I highly recommend at least a peak at this bag.
