I think the term “battle belt” is a little misleading. All the use cases shown in this thread are either range belts or maybe supplemental belts.
I think Battle Belt is much more appropriate for LBE type belt/suspender setups where your entire combat load is on your belt.
But for belt use with a plate carrier, I’ve used both ATS war belt and the Velocity Systems Operator Utility belt.
The ATS belt is good for an LBE setup with suspenders or as a range belt, but is too bulky to use in conjunction with a plate carrier.
The VelSys belt is a lot better in conjunction with a plate carrier, but still a little on the bulky side. I’m sure it would be great for guys with taller torsos.
I’m tempted to try a new slim one like the Ferro Concepts Bison belt. When running in conjunction with a plate carrier, I try to really minimize what I have on the belt, so it could work out.
