The equip region is an item attribute in the client schema used to identify the region where an item is attached on a character model. The equip region attribute (denoted by the value name equip_region) is given to all hats, miscellaneous items and some weapons, and its primary purpose is to prevent items in the same region from being equipped simultaneously. Equip regions were introduced to avoid visual clipping errors upon the addition of two usable 'Misc' slots.There are 24 equip regions in total. The equip regions of hats, miscellaneous items and weapons vary, but all hats have a base equip region of hat or whole_head.
