Frequency Mark Heavyweight Tee

The visual signature of sound.

Sound leaves marks not just in memory, but in how we move, how we gather, how we experience the world. Jamaican sound system culture understood this—bass as foundation, rhythm as community, frequency as physical force.

This tee carries that mark—minimal design. Maximum meaning.

Sound Becomes Visible:
The frequency mark represents those moments when sound transcends audio—when bass becomes a force you feel in your chest, when rhythm creates movement, when music builds community. This is the visual language of Jamaican sound system culture: not just heard, but felt, seen, carried forward.
