The account will be based out of McCann's New York headquarters, and the agency has a brief to develop a global consumer brand communications strategy and create a platform to allow the brand to grow.
DuPont Textiles & Interiors, owner of the Lycra brand, is thought to have seen five agencies for the task, including Saatchi & Saatchi.
Linda Kearns, global brand manager of Lycra, said: "The strategic and creative insights that McCann demonstrated, along with the strength of the McCann global network, convinced us that it is the ideal partner for our aggressive global plans for the Lycra brand."
McCann-Erickson already handles DuPont's corporate advertising, an account it won in 1999 and now runs globally.
Lycra is a stretchy fabric that is used in underwear, hosiery and swimwear, as well as ready-to-wear clothing.
