Skullcap (3.5e Equipment)
From D&D Wiki
 Skull Cap
A skull cap is a type of head covering that fits close to the head. A one-piece, full-covering skull cap must often be made to measure to the head it is made for. The most common colour of a Skull cap is black. It is sometimes worn by men who are tonsured or have male-pattern balding.
