Shoulder and back suspension mean a EVERYTHING as far as carrying-comfort goes, and the old bags were literally little more than unstructured bags with shoulder straps, and lumpy places where gear could dig into you.
I have always really liked having a separate compartment for sleeping gear, it just makes sense and keeps things clean.
I miss having a couple (or more!) side-pockets because they provide quick and easy access to things, but there’s (1.) a grab-handle for quick Zombie-getaways,(2.) a couple semi-hidden zipper side pockets good for single-stack magazines and maybe a small .38,(3.) a fairly useful internal/external double top-pocket,(4.) an internal flap for a 2-litre hydration system, and (5.) a rain-fly to keep it dry.
I’ll get these packed-up and take some more shots when I’m done.
