Goku, Krillin, and Yamcha wear the Turtle School uniform. This Gi is orange and has the Turtle School symbol on it. Goku wears this Gi in every major battle he fights in. During the Dragon Ball Z series, the symbol on Goku's Gi was changed to King Kai's symbol, the Son family's "Go" symbol, and later disappeared.
King Piccolo, Piccolo, and Gohan wear a similar purple Gi with Namekian shoes. During the Fusion Saga of Dragon Ball Z, when Gohan goes back to Earth after getting his power awakened, he asks Kibito to make him some clothes just like his father wears, so Kibito gives him an orange Gi, referring to the color as similar to that of the dropping of the frogs from planet Popol.
Goku's second son, Goten, also wears a Gi similar to that of his father. Near the end of Dragon Ball Z, Goku's granddaughter Pan is also seen wearing a Gi similar to that of the Turtle School but with no symbol, while Goku now wears a green Gi. In Dragon Ball GT, Goku's student Uub wears a green Gi, while Goku now wears a blue Gi which resembles his first Gi that he wore in the beginning of Dragon Ball. After the Shadow Dragon Saga, Goku Jr. wears Goku's old Gi. Other characters in the series who wear this type of clothing include Kid Trunks, Mr. Satan, and Vegito. In Dragon Ball Super, Goku Black wears a Gi with a black, grey and red color scheme and white Supreme Kai boots which is listed as the Dark Gi in Xenoverse 2.
