"Expansion Pass Bonus. A shirt with the Nintendo Switch logo on it. It's a rare article. If you sell it, you can't get it back, so wear it with pride!"
The Nintendo Switch Shirt is chest gear that appears in The Legend of Zelda: Breath of the Wild. It doesn't appear as a set, and it can only be obtained by purchasing the DLC Expansion Pass for the game.
Simply put, its a red shirt with the Nintendo Switch logo on the front, complete with a black strap that runs across the torso. It shows a bear resemblance to the Old Shirt that the player obtains at the beginning of the game, but in better condition. Unlike other Armors in the game, the shirt cannot be dyed, or upgraded at the Great Fairy Fountains.
The shirt can be found in a black chest with gold lining with "EX" written on it, on top of a wall near the Ja Baji Shrine on The Great Plateau. It can only be obtained by purchasing the DLC Expansion Pass.
