I had a Wilderness Tactical? belt that was real good. Most of the good nylon belts have a size limit far as minimum and maximum but they are perfect for what you describe. I out grew mine, actually I think it shrunk.
I think Brownells is carrying some nylon stuff now also that might be a good option. I can't remember whose stuff it is.
I just confirmed with one of the guys, Wilderness and Blackhawk now offer the 1 1/2" version. The Blackhawk has an extra D ring on the front that I would cut off since it interferes with my belt loops and my helicopter repelling days I think are pretty well over.
