Founded in 2003, Tsunami Sport has built a reputation as a sustainability focused teamwear brand for any athlete at any level. Its main focus is providing teamwear kit for clubs, schools, corporates and events with a considerable increase in the provision of sports uniform items to schools alongside their traditional custom design sports teamwear. With a focus since 2005 on the use of sustainable fabrics made from repurposed bottles they are a teamwear industry leading brand in minimising environmental impacts in the otherwise traditionally wasteful garment industry, with made-to-order garments and significant reduction in the use of packaging as key commitments in their approach. Since 2015 alone the fabrics used in Tsunami’s sublimated sportswear garments has increased from 55% to over 80% sourced from recycled PET. Based in Hong Kong and New Zealand, the company has a global network of clients.
