FOSSIL FLEX MODE garment-dyed heavyweight t-shirt
Flex like your bones are 65 million years old—and still cooler than half the gym.
The FOSSIL FLEX MODE tee is your badge of prehistoric power. It's for the legends who lift with ancient swagger, strut with Jurassic drip, and know that true strength never goes extinct.
Made with heavyweight fabric and heavyweight attitude, this shirt tells the world: fossils may be old, but the flex is forever.
Wear it when you hit the gym, the couch, or the tar pits. Whatever your vibe, make sure your fossils are flexin'.
