I use this:

Wenger Synergy Backpack, Gray (GA-7305-14F00) https://www.amazon.com/dp/B000NONHYY/ref=cm_sw_r_cp_apa_dsG5BbC6N7FMJ

Is has a padded compartment for your laptop. The middle compartment is perfect for a headset and ipad. There is a small padded zipper pocket ontop that will hold a stratus. It has these tall zipper side pockets that run basically the full height of the bag which are great for a fuel strainer, ipad mount, and a couple of screwdrivers. It also great organization for the little stuff. It is very rugged. I've had mine about 3 years and it still works perfectly. Highly recommend.
