Frequency Mark Sweatshirt

Sound doesn't just move through space—it leaves marks.

Jamaican sound system culture built more than parties. It built movements, communities, and revolutions. The bass you felt in your chest at a dancehall session wasn't just music—it was a frequency that changed how you moved through the world.

This sweatshirt translates that energy into form. Minimalist waveform graphic. Maximum cultural weight.

Premium heavyweight fleece engineered for comfort and longevity. The Frequency Mark graphic represents the visual signature of sound—those moments when rhythm becomes visible, when bass becomes physical.

About Sound & Movement: Jamaican sound system culture pioneered how entire communities experience music—not as individual listeners, but as collective participants. The frequency mark on this piece represents those invisible forces that shape culture: the bass lines that unite crowds, the rhythms that spark movements, the sounds that leave permanent marks on how we move through the world.

Designed with restraint, built for longevity. Carry the culture.
