This appears to be the company's first long sleeve (or possibly three-quarters) sleeve offering. Curiously as well, the shirts are essentially opposites. Where the sleeves are red, they are blue. Where the squares are dark/light orange they become dark/light blue. It's the same for the collars.

It is interesting to see such directly opposite colors creating a varient shirt. The Sonic is printed on, and is standing infront of gradient shaded rounded boxes, forming a large 'pixel' "X" for Sonic X. The logo of course, is in the corner, as they generally like for this to be pretty big among the designs.
