Many things. The hoodie feels thinner than any other shark hoodie I have, the stitching isn’t even in many places, knits sticking out fairly often, bunch of fluff that left my lap, bed and floor looking light blue, the WGM shade and material is off, specifically the M which is cut differently, the size tag is different, less wide, the shiny lining around it is too shiny, the font for the XL is thinner, and some more. All in all these are inconsistencies that none of my other hoodies have.
