For the last decade or so I have worn Wilderness Frequent Flier belt. When you order, call them and tell them you want them to sew velcro on the outer surfaces to mate up with your duty belt. When I got my first one i was considerably smaller in the waist and my duty belt felt like it was welded in place. I had a couple of belt mounted items that wanted to slip, and applying industrial velcro to those items locked them in well enough. Now that I am a bit larger, and losing weight I notice a little sag at 11:00-1:00, where the belt secures to itself. When I get back down to where I want to be weight wise I will likely need a new one as the overlap is creeping wider as my waist gets narrower. I am on my second kne and don't regret either.
