This is called the "Hidden Hedgehog Hoodie".
It is by Bio World, released for 2021. What's nice about it, is that it's in mens' sizes only so that it will fit anyone. It has the usual 'kangaroo' mono pocket in the front, long sleeves, and draw string hood. It's all a dark blue. The 'hidden' part comes in with the graphic for the front which is fully shaded finger waving classic Sonic, but they don't give him any outlines so he just appears as a triangle, the face & hand. He's meant to be camoflaging into the shirt itself. It spells out his name in Japanese letters below in blue as well, but these do get an orange background so you can actually read it. It's an ok idea, if you didn't already have something similar.
