I'm a big fan of Klein Tools for their clever Katapult Wire Stripper, and I'm happy to see the company has applied their design talents to tool bags as well. Their Tradesman Pro Tool Master Backpack has a host of great features that show the designers have studied how tools are hauled and used in the field.

It's got a beefy handle supported by aircraft cable; a molded plastic compartment up top to protect breakable items like safety glasses and smartphones; a molded plastic base so that the bag remains upright when placed down, and keeps it up off of standing water; an integrated hook so the bag can be hung in place and used like a locker; a removable tool caddy that can also be hung; and tons more features.
