I use the Blue Alpha EDC Low Profile belt (bought via the WPS website), and so far, so good. I initially ord'd the belt in my pant size, but after receiving it and trying it on with a IWB holster (AG 4.0 Shape Shifter), there wasn't enough belt left to fully connect the velcro closures together. Contacted them, and explained my predicament, and they promptly sent me the next size up, and a return shipping label to return the original belt. Very good customer service, and the next size up has worked well since then for IWB and of couse OWB carry. Now, thinkibg back however, the Alien Gear 4.0 IWB Shapeshifter is a bit bulky, and maybe it's how it "fits" my particular body, which is 6'0", & 197-200lbs (on any given day)
. Not questioning their sizing charts/advice, the next size up from my pant sz works.
. Hey, it's the only belt I use for "carrying", so it's evidently working.
