As the name suggests, the Simple Hauberk is just that - nothing too fancy. With chainmail on the shoulders and upper arm, the rest is mostly fabric. A bird of some description is outlined over the collarbones too.
Anyone looking to dye this may be a tad disappointed though. It looks like only the shoulders and upper arms really respond to your colours. The Wiki shows this cosmetic on a Hobbit and dyed black.
The Simple Hauberk, despite being full-length, is not quite a full set. If you want boots, you'll have to supply them yourselves. And I haven't checked if you can use gloves on this item or not.
