More importantly, what it is, is a Gouf. An extremely cool design features the Gouf seen through a slash it's just made with a beam sabre, and the text "Zaku to wa chigau no da yo. Zaku to wa!" (Basically, "This isn't a Zaku. Not a Zaku!"). Printed on a white T-shirt, 100% cotton, size M. Please note that Japanese sizes tend to run a half size to a full size smaller than North American sizes; keep this in mind when ordering (sizing chart is linked above).
