Fast Retailing Co is set to launch its sports brand Body Tech by the start of July.

Fast Retailing - which operates the Uniqlo casual clothing chain - will sell 22 pieces priced between JPY1,000 and JPY2,990.

The lines were developed in conjunction with the Sports Medicine Research Centre at Keio University.

Fast Retailing hopes to gain a 10 per cent share in Japan's JPY400 billion sportswear market.
