Blackhawk CQC, a fine product indeed.
It's not going to wear down like leather does, and if it happens to get soaked by perspiration, then all it needs is a soaking in soapy water, and a rinsing. Very strong and stiff, and . I have one that I'll start using once my custom made leather belt wears out (been using it for 10 years, and I may have to replace it in another 10).
That being said, I still slightly prefer my thicker custom made leather belt (done at a gun show), or something by Mitch Rosen or Milt Sparks when using it with my Kydex Sidearmor holster, because the thickness prevents the holster from twisting a bit, since the Kydex belt loops aren't flexible at all. No such differences with my leather holsters, though.
