Los Pumas play in a hooped shirt in the country's flag colours of sky blue and white with sky blue sleeves, white shorts, and hooped socks in sky blue and white.

Reporters were trying to devise a catchy nickname for the team similar to existing international team nicknames such as All Blacks, Springboks, and Wallabies. One of them saw the picture of an animal on the UAR crest; however, he thought it was a puma instead of the actual jaguar. The mistake stuck, and was eventually adopted by the Argentines themselves (although the UAR crest still depicts a jaguar).
