From ThresholdRPG Wiki

While in many games, armor is associated with a slot (legs, chest, head, etc), in Threshold, it is associated with types (suit, pants, gloves, etc).

Game balance

Armor is balanced around the idea that possession of it is fleeting. It is relatively easy to obtain and is often more powerful than it should be since Threshold operates on a cycle of reboots, whereby all gear is erased, notwithstanding the fact that, by and large, death is a very real possibility.

Typical armor slots

While occasionally there are other slots, these are the principals slots into which most gear fits.
