Where "Trackie Daks" Comes From
"Trackie-daks" combines two slang words: "trackie" is a clipping of "tracksuit," while "daks" comes from the brand name DAKS — a British clothing company that pioneered the self-supporting trouser waistband, reportedly combining "dad" with "slacks." By the 1960s, "daks" had become a generic Australian term for any trousers, and when paired with "trackie" it produces the compound that means tracksuit bottoms specifically.
"Trackies" is the shorter form — just the "trackie" clipping, stripped of the "daks" component. Both forms sit in the tradition of Australian English that folds brand names, body words, and clothing terms into informal compounds: "underdaks" (underwear) follows exactly the same pattern and has itself become a brand name, completing a circular journey from noun to trademark to generic and back again. No specific date for the first recorded use of "trackie-daks" has been established.
