The German sportswear brand that uses three parallel stripes as its logo is Adidas.
The three stripes are one of the most recognizable marks in sportswear. They commonly appear along the sides of Adidas shoes, tracksuits, shirts, and other athletic products. The branding was adopted early in Adidas’s history and became closely associated with the company’s founder, Adolf Dassler.
Adidas was founded in Germany in 1949. Historical accounts say the company acquired the rights to use the three-stripe design from Finnish footwear company Karhu in 1952. Adidas later developed additional marks, including the trefoil logo introduced in the early 1970s and the mountain-like performance logo used across later product lines.
The stripes themselves are not the same as the trefoil or the three-bars performance emblem, although all are Adidas branding. Another common confusion is Puma: it is also a German sportswear company, but its best-known logo is a leaping puma rather than three parallel stripes.
