Here is a hat from Spencers Gifts in 2019.
It seems fairly well put together, with a nice, thick all-embroidery Sonic on the front, and an all-over golden rings design for the black background...however, the art it uses isn't the best. This baseball cap style hat has the "he died" classic Sonic sprite among the rings design...
But, as any fan knows, when Sonic loses his rings he doesn't die...that's the whole point of having rings. Also, the art is neo-classic (ish?) and kind of odd, with his spikes shown as fairly far up, and a wierdly shaped mouth/front of face. It's an ok concept, but a strange execution with wrongly applied art.
