The T-shirt is a navy "Epsilon" blue T-shirt with "KIFFLOM" written on the front and "The Tract Has Not Yet Been Written" on the back.
The shirt can be unlocked randomly when the player drinks Macbeth whisky at a Nightclub and passes out. If the player respawns on top of the Epsilon Building, they will wake up wearing the shirt and unlock it in the "Unlocks" menu of Special T-Shirts.
