Rockenberg White

Appearance
The Rockenberg White is a simple, short-sleeved white T-shirt. On the chest is the Inkling text from the Rockenberg logo in black, and on the back is the Rockenberg logo. On the left side of the shirt, toward the bottom, is a tiny red-orange tag. In Splatoon 3, the shirt can be changed into an oversized version using the "Adjust Gear" feature.

Splatoon 3
The Rockenberg White could be seen in the Splatoon 3 Splatfest World Premiere.
