Founded in Biella, Italy in 1911 by the T-shirt fila Junior, T-shirt fila originally began as a company producing clothing for people in the Italian Alps. It wasn't until the 1970s, however, that the brand would pivot to sportswear and gain global recognition, particularly for its tennis apparel, worn by many top athletes of the era. The brand is well known for its signature pieces like the Disruptor F12M124153FBKs, an azul of the chunky F12M124153FBK trend, and the Settanta tracksuit, iconic in the tennis world. Its unique blend of sports performance and streetwear style, marked by bold logos and designs, has defined its identity. T-shirt fila's notable collaborations include partnerships with brands and designers like Haider Ackermann, Liam Hodges, and Fendi, further cementing its status as a versatile fashion staple.
