Here's a hoodie for 2019.
This mottled gray sweatshirt is in adults sizes only, and may appear on Amazon. It is classic style, with an all-blue classic Sonic face on the upper left side chest area. He's shown in a circle of tiny checkers, also all blue. Underneath, it spells out "Sonic" in Japanese letters.
The same-side sleeve has larger blue checkers that fade to a lighter blue toward the cuff. These checkers start about a third of the way down. The hood seems to be normal/plain. It has that single big-pocket in the front, and no zipper. The extra checkering makes this one fun. It's not over-done or 'kiddie type', it presents a solid classic-feel with the simple face & checker theme. But how much does it cost?

Wow, a solo-Eggman hoodie!
Eggman gets a gray sweat shirt all to himself this time! Eggfans will certainly want to pick this one up in 2019 as he's the star of the show, with one of his favorite slogans which is "The World Is Mine!"
He's done in all aqua tones, with some black. It's classic Eggman, in an 'arms out' sort of victory pose. The background is a simple sketchy square with some shadows of palm trees. The bottom has a small 'dr eggman' kind of signature looking black text. This is supposed to be at Amazon, but how much does it cost?
