The Adidas Tango is a matchball that was originally developed for the 1978 FIFA World Cup; held in Argentina. The Tango has been released in a number of versions; depending upon the tournament in which it was designed for. The Adidas Tango - alongside the TELSTAR - is Adidas' only matchball that has been designed and re-released for multiple FIFA World Cups and international football tournaments; therefore, the TELSTAR and Tango are Adidas' most iconic matchballs. The following is a list of Adidas Tango tournament matchballs:

The Tango replaced the TELSTAR - used at the 1970 and 1974 World Cups - the TELSTAR and Tango are designed with hexagon (six sided) segments and a few pentagon (five sided) segments. While the TELSTAR had segments alternatively painted black or white, the Tango used a tridant design; the Tango tridant was later incorporated into the Azteca matchball for the 1986 FIFA World Cup.
The original Tango matchball - the Tango Durlast - was made from leather and had a durlast (high quality polyurethane) coating. While the Tango ball was always designed with a waterproof coating, it was not always effective: the ball sometimes needed to be replaced during matchplay, and the Tango did not perform anywhere near to the standard of modern Adidas matchballs.
The Tango is currently in production - unlike other Adidas FIFA World Cup matchballs - and has been released in a range of new versions: such as the Tango 12 and Tango Rosario. While the design of the modern Tango football is identical to the older balls, the materials and technology used in it's construction is different.
