I worked with an X Large Ortlieb Express Courier bag for my last two years....it was the best courier bag I ever had, but a bit sweaty on the back in Summer and the strap system wasn't too comfy.....however it comes with tons of webbing and rings in each corner so you can set it up how you want....100% waterproof, and super tough!
