The barbarian male has like 20 different meshes. A Naked, Light, Medium, and Heavy Armor set. Each set has like 4 meshes with it. Though you don't necessarily have to match them with their respected set.
Without looking at them I think they have a Boot, Glove, rest of body, and a cloth tabard like mesh for each set.
Sounds like how it is with WoW character models. Which prevents me from doing every glove, boots, pants, etc.
