The Substance Line represents the core of Underground & Sound, no noise, no hype, just pure style. Inspired by 90s subculture and terrace fashion, these T-shirts are built on authenticity, attitude, and timeless design.

Each piece is crafted from premium cotton with a focus on fit, comfort, and lasting quality. Clean cuts, bold graphics, and understated details give every shirt a classic yet contemporary edge, wearable statements that stand the test of time.

This isn’t fast fashion. It’s Substance. For those who know their culture, value quality over trends, and wear their identity with confidence.
