I've been asked this enough times it's worth writing down. Not what you should carry — what I actually carry, every day, on commercial work. This isn't a gear wish list. It's a field audit.
The Bag Itself
Klein 80028. 28-piece backpack set. I know, it's a kit — and kit-tool skeptics are right about most kits. This one is the exception. The backpack itself is built for the trade. Wide mouth, rigid structure, MOLLE straps on the outside for clipping on. The 28 pieces that come with it are a genuine working set, not filler.

I keep an ACES 14-piece insulated kit in the bag at all times. Not because every job is energized work — because you don't always control what the job becomes. A set that's rated 1000V and tested to IEC 60900 costs less than a hospital bill. The math is simple.

The Rack-A-Tiers Wire Tub lives on every job. You're pulling wire constantly — you need it dispensing cleanly, not tangling on the floor. This thing does exactly that and takes up almost no space in the truck.

Everything I don't use every day lives in the truck, not on my back. A heavy bag slows you down. Prioritize what gets pulled on every job: testers, insulated hand tools, wire management. Everything else is truck stock.
