H.a.m. shirt

The H.A.M. shirt is a shirt worn by H.A.M. (Humans Against Monsters) members. Wearing it increases the chance of successfully pickpocketing a H.A.M. member. It can be a obtained by thieving H.A.M. members or by killing H.A.M. Guards. H.A.M. clothing is usually worn for show, although it is a requirement for The Lost Tribe and the Death to the Dorgeshuun quests.

Players can store the shirt, as part of a full set of H.A.M. robes, in the Armour case of the Costume room of a Player-owned house.

Interestingly, while it shows as having midriff on a female NPC, it does not on a female player character.
