Well I carry alot of stuff everyday for work and was wondering what every one has found to be a good EDC bag. Currently I have a Samsonite bag that is falling apart so I think I want to upgrade. The hope is to be able to carry a letter size portfolio, a small bag with tools for working on electronics (wire cutters, screw drivers etc for computers), headphones, power pack and possibly a laptop. I have been thinking of going to a backpack and have eyed the Mission Workshop ARKIV bag but I was wondering if there could be a cheaper alternative that gets the job done.
