The hoodie variety continues with these 6 sweat shirts. There are 2 with the Forces Eggman Empire logo which are opposites of each other. There's red with black logo, and black with red logo. It's a simple circle for the chest area of the draw-string hoodie.
Next is the "Gold Crest" which is another highly detailed line art (in gold ink) of Modern Sonic in a ring with a focus of many, many rays toward a ring he's holding. There's Japanese text on one edge. (What does this say?)
The next 2 are just a color variant of each other. They both have the same design which is the classic logo with classic face & "91" which is split up by 2 'hit' midway-point gate posts. It's a little hard to tell what these are on the shirt because they're usually depicted as 'unhit'/up as the more gate-looking configuration but here they're shown in the spinning/folding phase. The only difference here is one is blue & the other shirt is white. The last one is the "Emerald Club" Sonic & Knuckles detailed line art. This time, it is white on a black background.
All of these are adults sizes & available in the SegaShop in 2018, priced between 40 and 50 dollars.
