I use a Maxpedition Colossus verispack for my EDC bag. The bag can fit a decent amount of gear and is modular as it has various attachment points for molle accessories.
Maxpedition gear is very heavy duty, some of their bags have a sewn in rain flap to keep water out of the bag, and they are all coated in Teflon so water beads right off. The main compartment is padded and reinforced.
For 2016 Maxpedition is coming out with a newer high tech looking molle pack line. I just got email from them yesterday The 2016 Shot Show is coming in 4 days and will give you a preview of all the new bags, gear, and firearms coming out this year. People will start loading up youtube videos on day 1.
Are you looking for a shoulder bag, backpack, or sling style courier bag?

Apparently the Rock has good taste in man bags. I posted this pic so you can get an idea of the size. The rock stands at about 6ft 5in tall.
