Here's a first!
This is likely to be the first actual merchandise for Sonic Movie 2. It makes sense, because it is a "Crew" item, which means it was never for regular retail sale. It was distributed only to crew members/workers on the movie itself/shooting area. It was likely in Hawaii where part of it is set.
The hat itself is all black, and it is a 'trucker style', which means it has a mesh back and only 2 solid panels in the front. The bill is slightly curved, and the sticker proclaims it as a snapback style. The movie's logo is embroidered on. They use the "Tails' Tails 2", that Sonic 2 the game did. It remains to be seen if this movie will be any good. This hat appeared in September 2021.
