Well it arrived and I've worn it for IWB a few times now. I like it. It's more comfortable than my X-Concealment belt. I have to say that when it arrived I was like "WTF? Those APS guys lied to me!" When I took it out of the box, it felt overly flexible, even limp compared to my X-Concealment.
The X-Concealment is literally at least three times as stiff. If I take my pants off with that belt still in them, you can't fold the pants because the waistline holds a round shape, similar to my thicker leather carry belts. The Wilderness belt has a lot more give, and I was afraid it wouldn't hold a full-size pistol well. But it did, and with the greater flexibility, it didn't dig into me in the sitting position the way the X-Concealment sometimes does. Anyway, good call guys. :)
