"Clothing resembles the gi Goku wore when training with Whis in Dragon Ball Z: Resurrection ‘F’."
The Whis Symbol Gi's design is partially based on Goku's Turtle School Uniform though is a somewhat lighter shade of orange, lacks an inner shirt, and features a different styled obi, boots and wristbands. Though originally created by Whis the gi initially lacked a kanji, but while sparring with Goku and Vegeta on Beerus' Planet, Whis playfully signed the front of the gi with his symbol showing off his superior speed. The symbol is actually Whis' signature and was drawn using a permanent marker. Whis also did the same to Vegeta's Whis Symbol Battle Armor.
Goku also wore this gi during the Tournament of Destroyers in Dragon Ball Super. After the competition, Goku returned to wearing his regular outfit.
The Whis Symbol Gi made its original debut in Dragon Ball Z: Resurrection ‘F’ . Like in the anime, Goku wears the Gi while training under Whis, during which Whis uses his speed while sparring with both Vegeta and Goku, to sign their clothes with a permanent marker and Goku later wears the Whis Symbol Gi during his battle with the resurrected Frieza.
