The Constant

$25.00

This is the shirt that doesn’t need a second look. That is because it’s already decided.

Heavyweight black cotton. Small CranioDad logo on the left chest.
Right where it belongs. Close to the core. No explanation required.

You wear this when you’re not trying to be seen, but you still are.
For long days, late nights, travel, work, streams, and the in-between moments where consistency matters more than volume.

It’s not a statement.
It’s a baseline.

Reliable. Grounded. Unmoved.
