There is an alternate variant of this item called the Iron Yahar'gul Helm. It is essentially the helmet without the hood.
This Helm resembles two things in particular, the first is the visor which is an obvious nod to the popular helmet worn by Havel the Rock from Dark Souls. The second thing is the top part of the helm which seems appears to be based on a "Pith" helmet, a type of headwear used mostly by european huntsmen in tropical regions during the early 20th century.
Upon wearing the Helm, the hair on the player character's head will disappear, as if it were bald. This is visible by tilting the camera to closely examine the character's face.
