The THTC System of a Mau Hemp T-Shirt is a bold evolution of the iconic Chant Down Babylon design, created by graffiti legend Mau Mau. Inspired by reggae sound system culture and printed in classic Jamaican colours, this piece blends activism, art, and sustainable fashion. Many still call it the System of a Mau Hemp Tee, ensuring both terms remain connected to its legacy.

This t-shirt is crafted from 180GSM pre-shrunk fabric, consisting of 55% GOTS-certified hemp and 45% GOTS-certified organic cotton. Built to improve with age, the fabric is breathable, durable, and naturally hypoallergenic. THTC’s hemp range continues to set the standard for ethical streetwear, fusing strength with style.

For over 25 years, THTC have worked with trusted, ethical manufacturers, ensuring fair wages and sustainable production. Recognised as the UK’s most ethical clothing brand, they continue to lead the way in eco-conscious streetwear.

THTC & Fairtrade

THTC have always been pioneers in ethical and sustainable clothing, and therefore we are proud to feature their brand instore.

Their organic cotton products come from India in partnership with TeeMill, while their hemp is sourced from long-term partners in China. Furthermore, THTC collaborate with small, family-run factories, including one partnership lasting more than 20 years. These factories pay workers above the local living wage, provide standard 8-hour days, and ensure paid holidays.

Additionally, THTC regularly visit these factories to check working conditions and directly support the welfare of employees. Consequently, their commitment to fairness and sustainability is evident in every garment they create.
