Most of the things in that mod are stuff that I personally don't want (i.e. +5 long sword usable by mages, granting grandmastery; and a +12 Hackmaster). The thread and the readme mentions nothing about how you can acquire the pantaloons - with the exception of "gold pantaloons now droppable".
So unless the pantaloons is a separate component, it's not really up to par with that the OP want. Which, incidentally, I think would make for a nice component.
