Base 5 is a clothing brand that appears in Grand Theft Auto: San Andreas.
Base 5 hoodies are available from Sub Urban for $105, and they also sponsor Hotring Racers. There are signs, posters and photos throughout San Andreas advertising this clothing brand. One of the posters has a cartoon depiction of a thug who bears a striking resemblance to the late rapper Tupac Shakur. Another has a bull terrier dog next to him that resembles Chico from Next Friday. These posters can be seen in Ryder's house.
