I have a North Face "surge" backpack, Great bag for traveling. Stores both on my laptops, tablet, various tools and gee-gaws Like my label maker and crimper, chargers etc....and has pouch attachment loops.

Interesting. I was looking at tool specific backpacks and they all look kinda crap.
Since I'm using zipper pouches anyway, a big open bag like that would be good.
I have a goruck rucker 4.0. Maybe I'll take the plate out and try that on a couple of test jobs.
