Finally, an adults Sonic Pajama Set!
This is new for 2019, in mens adult size only, which means it'll fit anyone. That's great news for Sonic sleepwear because traditionally, everything was either kids or little kids. This has a light gray top with jumping twist modern Sonic stock art. The background here is a rectangle made of tiny round black paint spatters. Sonic is in 3 colors only: blue, red and white. (So, that makes his eyes white too, which looks a little odd because the shoes did get their color) His name is spelled out in Japanese at the top, then again at the bottom with 'the hedgehog' added.
Sadly, the pants, which are black, appear to be plain / generic without any Sonic fun stuff on them. It looks like elastic waist with draw-string top. You can see the branding in the back of the shirt collar. This set is 30 dollars on Amazon in summer 2019.
