Nothing major. He's just rocking the Leather look instead of Shiverback. Probably wrong in LOIO too, but haven't been over there yet.

It may be worth checking all the monk quest guys. Eejag and Kairen should also be decked in Shiverback. I can't remember what Eejag was wearing, and I haven't done the Kairen steps yet. I just remember this being wrong on Gwan too, but I've already reported it.
