We've had transforming Nike shoes.
We've had transforming Garu iceblocks.

Now, coming from Japan (where else?)... transforming Baseball Caps.

That's right, if you're a baseball cap collector, you can now have not one, but two, Transformers hats.... an Autobot version in Optimus red/white/blue colours, and a Decepticon version in, well, black/white.

Teaming up with "New Era Cap Company" TakaraTomy will be releasing these, but a release date is not yet known.

Images of the prototypes and the colour drawings can be seen here.

NOTE - just like the shoe Transformers, these are not going to be wearable, because of the robot bits inside the hat "shell".
