It is actually the Breton cloth armor, and anyone with the motif can craft it.

Yeah, what he said, it's pretty awesome looking and I in fact have taken to wearing a few pieces of cloth on my head and belt with a few points in light armour for the small magic buff to compensate for the drop in armour points from medium.

In fact, I've been mostly using magic anyway, stamina just doesn't seem worth it on a Nightblade even with a duel wield/bow build, and stamina regen seems much more important with dodge using a percent rather than a set value.
