Gym Rat T-shirt

This Gym Rat shirt takes the classic 1928 Steamboat Willie cartoon style and cranks it to max volume with a fully jacked redesign. Featuring a muscle-bound vintage rodent, this tee is made for lifters who live for the pump and don’t mind showing off a little cartoon chaos. The bold black-and-white design gives it that timeless, retro animation look—now paired with modern gym rat energy.

Printed on a comfortable, durable tee, it’s perfect as a pump cover or everyday flex wear. Whether you're smashing weights or chilling post-lift, this shirt delivers classic style with heavy meathead attitude.
