Hahah, just wanted to show it for the pic. Here's a link to the belt for ya.
I made my own version of this with an old ratchet strap. I'm going to redo it once I have the time, with a newer strap and the buckle from this (literally the same belt alyx studios make). It's one of those things that's really easy to diy though, and you can add your own personal touch to it!
