Athletic began playing in an improvised white kit, but in the 1902–03 season, the club's first official strip became half-blue, half-white shirts similar to those worn by Blackburn Rovers, which were donated by Juan Moser. Later, a young student from Bilbao named Juan Elorduy, who was spending Christmas 1909 in London, was charged by the club to buy 25 new shirts, but was unable to find enough. Waiting for the ship back to Bilbao and empty handed, Elorduy realised that the colours of the local team Southampton matched the colours of the City of Bilbao, and bought 50 shirts to take with him. Upon arriving in Bilbao, the club's directors decided almost immediately to change the team's strip to the new colours, and since 1910, Athletic Club have played in red and white stripes. Of the 50 shirts bought by Elorduy, half were then sent to Atlético Madrid, where Elorduy was a committee member and a former player; it had originally begun as a youth branch of Athletic Bilbao. Before the switch from blue and white to red and white, only one other team wore red and white, Sporting de Gijón, since 1905.
