Howdy! I'm a newbie here but not particularly to EDC. I'm trying to find a comfy bag (preferably a bag with one strap) that I can sling "over the head" and on the back. I'd like to put some soft level IIIA AR500 armor and a laptop in it, so something moderately big. MOLLE would also be helpful. And lots of Velcro, for the patch- in me. Any suggestions?
