Meet our suppliers


Better choices come from taking responsibility for the places and communities we touch, and the suppliers we work with. We’ve been collaborating with many of the same partners since 2007, from our denim specialists in Turkey and cotton growers in India to our manufacturers in Portugal and Romania. Working with such a diverse range of partners, whether that be small suppliers specialising in traditional techniques or larger-scale factories with a focus on new technologies, means we have a tremendous amount of shared expertise and passion to take on the future and its challenges together.
