Well here's a busy tee. It's 100% polyester, so the Green Hill design is sewn into the fabric, rather than being applied, like most shirts. It has various Sonic, Knuckles, Eggman Egg o Matic & motobug sprites scattered about & in different poses. Notice Sonice 'die' pose getting shot at by a Buzz Bomber too. It may be busy, but is likely durable due to how it was made. Photo discovered by ShadowFoxx757

Remember the modern neon line colors Sonic tee? On the right it is in classic style. This one is a mens' size too, not just kids so anyone can wear it. Either Sonic looks decent with the hot color treatment.
