It's comfortable, and easily modified.  I prefer leather belts, but when I know I'm going to be in humid, soggy, muddy environments, I'd rather have this synthetic belt, knowing that it can be repurposed as an adjustable strap for multiple purposes if I'm in a jam hiking or at a remote worksite.  I haven't used it  (and probably won't) for a tool or weapon belt, though I might use it as a backup device for water or rapid entry dive rescue work.
