The striking jersey has been commissioned to mark the 25th anniversary of rugby unity in South Africa.
The red Springbok jersey completes a "jigsaw puzzle" of playing and training apparel that was prepared for use in 2017.
The colours of the flag – green, yellow, blue and red, as well as black and white – have all featured in training or playing apparel this year.
SA Rugby CEO Jurie Roux said that the red jersey was a symbol of the conclusion of one era and the starting of a new one.
"It is commonplace for national teams to be creative with their alternate playing kits but it is not something we have done with our white alternate jersey in South Africa before.
"The traditionalists might miss a heartbeat but we need to move with the times as a sport and it's 111 years since a South African rugby team first wore a white jersey so it's not something we've rushed into. We think this makes a statement, it will definitely be a collector's item," said Roux.
