A leather jacket is a vertical oblong with long sleeves protruding from the upper sides and extending down. The sleeves reach lower than the bottom of the jacket's hem. Its normal (un-dyed) color is a dark, reddish brown.
When worn, a Blockhead's environment bar and happiness bar will steadily decrease at a slower rate than an unequipped Blockhead or with linen clothes. Over time, if a leather jacket is equipped on a Blockhead, the jacket will slowly degrade and eventually be destroyed. Leather jackets are able to be dyed to customize the appearance of a Blockhead.
