Here's a cool school bag by GE Entertainment. It has just the head of classic stock Sonic, with the classic logo as well. The blue checkered background is reminiscent of the old games, but it's given a modern twist with the black design at the bottom creeping over the checkers. This bag is a single shoulder style, with fold over clip-able flap. Seen in 2009.

While the one in the gallary is a Messenger Bag, it can still be used for school. Once again the top folds over and clips but it's more square than rectangle. It has Sonic Adventure style Sonic in a new pose, skidding into a paint splash type effect. "Sonic" is written as the background in a more grunge-style font for a modernist look. This bag is also made by GE Entertainment, and is available at www.animewild.com and www.gkworld.com sold in 2009 It should be around $30.00 when you order it.
