Look at this!
This shirt is quite special--it features the first (known) clothing appearance of E Omega, Blaze the Cat and Rouge the Bat! You can also see Silver, Eggman and Amy, and of course Shadow, Tails, Knuckles and Sonic. A busy shirt with quite the cast! All done in CG Cutscene-style art. If you're a fan of any one of these guys, this shirt is a must-have for you! It (rightfully) pulls the 360 Sonic logo in at the bottom. Shirt available at Sears 2008 fall/winter. There is a variant of this in white short-sleeve, with the exact same graphic.

Like the previous one, this shirt is really pulling in the cast members. It has Blaze the Cat, Tails, Amy, Knuckles, Silver, Shadow and Sonic. Being red, Knuckles doesn't do too well on the red shirt with black long sleeves. This shirt features the more thought of as "heroic" characters, rather than just throwing everyone onto a tee. If you look closely though, you can tell they used the exact same art for both of these shirts, they've just re-arranged where everyone is placed. Still, another must-get for fans of the characters who don't get to appear in merchandise much. Shirt available at Sears 2008 fall/winter.

This action filled shirt is great...if you're really small.
This is another little-kids only one, this time with Silver, Shadow and Sonic shown jumping. Another game-type render, this graphic looks good! Plus, it's full of new poses, sure to keep things interesting. This same trio appears standing on a teen size tee, but that is not a variant of this.
This shirt introduces something new (though it can't be seen in the photo) "Thermal Fabric" is used on the long sleeves. This textured fabric is warmer than regular tee-fabric.
